Best Iridium Spark Plug for Your Bike (2026): NGK vs NGage, by Model

The best iridium spark plugs for bikes in India in 2026 are the NGK Iridium IX range and the NGage Double Iridium range, from ₹515 for a single plug. An iridium plug uses a very fine centre electrode that fires a stronger, more focused spark and needs less voltage to do it, so cold starts are easier, idle is steadier and the plug lasts far longer than an ordinary nickel one. What matters is fitting the exact plug your engine was designed for, in the right heat range, in the right quantity. This guide lists the correct plug for every model we stock, explains how to read a plug code, and shows you which bikes need more than one.

A note on prices: every price below was current when this guide was last updated. Spark plug MRP moves from time to time, and our selling price moves with it, so treat the product page as the final word rather than this page.

NGK or NGage: which brand should you buy?

Two brands lead the Indian market, and both are genuine iridium. They are not really competitors so much as two different answers.

Brand	Range	Construction	Best for	Price
NGK	Iridium IX, Laser Iridium	Iridium centre electrode, nickel ground electrode	The original-equipment standard. The widest fitment range by far, and the only option for older and commuter bikes.	₹515 to ₹905
NGage	Double Iridium	Precious-metal tip on both the centre and the ground electrode	Modern performance bikes. Fewer part numbers, but each one is model-specific and made in Japan.	₹899

If your bike appears in both columns below, either is a sound choice. NGK is the safer pick if you want to match factory specification exactly. NGage is the pick if you want the longer-wearing double-iridium electrode and your model is on their list.

Find the right iridium plug for your bike

Every plug below links to its own product page with current stock and price. Where a bike takes more than one plug, the quantity column tells you how many.

Royal Enfield

Model	Plug	Qty	Price
Classic 350, Bullet 350, Meteor 350, Hunter 350, Goan Classic 350 (J-platform, 2021 onward)	NGage DH7RTII-8	1	₹899
UCE twin-spark 350 and 500 (BS3 and BS4): Thunderbird 350 and 500, Classic, Bullet, Electra	NGK BPR5EIX + CPR6EAIX-9S kit	2, different parts	₹1,730
Single-plug UCE: Classic 350 and Bullet 350 BS6, 500s BS4, Continental GT 535	NGK BPR5EIX	1	₹865
Himalayan 411, Scram 411	NGK CR7EIX or NGage B8RII-8	1	₹865 / ₹899
Interceptor 650, Continental GT 650, Super Meteor 650	NGK CR7EIX or NGage B8RII-8	2	₹865 / ₹899 each
Shotgun 650, Bear 650, Classic 650, Bullet 650	NGage B8RII-8	2	₹899 each
Himalayan 450, Guerrilla 450	NGage BN8RTIIA-9	1	₹899
Cast Iron Bullet 350 (pre-2008, not UCE)	NGK BR6HIX	1	₹865
Bullet LB 350 Machismo	NGK BPR7EIX	1	₹865
Bullet LB 500 Machismo	NGK BR9EIX	1	₹865

The 350 is the one people get wrong. The UCE engine (Classic, Bullet, Thunderbird up to around 2021) is a twin-spark and takes two different plugs. The J-platform engine (Meteor, Reborn Classic, Hunter, Bullet Reborn) takes one. If you are unsure which you have, send us your registration year and we will tell you.

On the 650s: NGK's own application chart names the Interceptor, Continental GT and Super Meteor for the CR7EIX. It does not list the newer Shotgun 650, Bear 650, Classic 650 or Bullet 650, which is why we point those at the NGage plug instead. The Bullet 650 is built on the same 648cc engine as the Classic 650, so it takes the same plug. They all share the same 648cc twin, so the NGK plug is very likely fine, but we would rather send you to the part the manufacturer actually lists than assume on your behalf. Ask us and we will check before you order.

Not sure which Royal Enfield engine you have? Our Royal Enfield spark plug guide covers every model from the cast iron Bullet to the 650 twins, how to tell the engines apart, how twin-spark works and when to change each plug.

Triumph Speed 400, Scrambler 400X, Speed T4	NGage VH8RTII-9	1	₹899

Bajaj's DTS-i engines run two plugs and the Triple Spark engines run three, one centre and two sides, and the centre and side plugs are different parts. They are not interchangeable. Buying the matched set is the way to avoid getting this wrong.

Honda

Model	Plug	Qty	Price
CB350, H'ness CB350, CB350RS, CB350C	NGK CPR6EAIX-9S	1	₹865

CBR250R, CBR300, Rebel 300	NGK SIMR8A9 Laser Iridium	1	₹905
CBR150R	NGK CR8EIX	1	₹865

The CB350 is worth a note. It leaves the factory with an NGK MR6K-9, Honda part 31916-K0Z-901, which is heat range 6. Much of the aftermarket sells the CPR8EAIX-9 for this bike, and it does fit: thread, reach and hex are identical. But it is heat range 8, two steps colder than the plug Honda fitted. A colder plug errs on the safe side and plenty of owners run one without trouble, so this is not a warning, simply a preference. We supply the CPR6EAIX-9S because it is the heat range Honda specified. The same plug is also the second of the two the Royal Enfield UCE twin-spark takes, which is why you will see it listed twice in this guide.

Bikes that need more than one plug

This is where most wrong orders happen. Count before you buy.

• Single-cylinder, single-plug. Most bikes. One plug.
• Parallel twins. The Royal Enfield 650s, Kawasaki Ninja 300, Benelli TNT 300, Yamaha R3. Two plugs, and you replace both together.
• Royal Enfield UCE twin-spark. Two plugs per cylinder, and they are different part numbers. A BPR5EIX and a CPR6EAIX-9S, not two of the same.
• Bajaj Triple Spark. The Pulsar NS200, RS200 and the Dominar run three plugs in one cylinder: one centre and two sides, again different part numbers. The centre and side plugs are not interchangeable and fitting them in the wrong position will affect how the engine runs.

Complete ignition kits

If you are opening the engine up anyway, the NGage kits replace the whole ignition path rather than just the plug. Each one pairs a genuine plug with a 5 kΩ resistor spark cap and an ultra low-resistance racing cable, which is where a lot of a tired ignition system's losses actually sit.

Bike	Kit contents	Price

Are iridium spark plugs worth it?

Yes, for most modern bikes an iridium plug is worth the money. Iridium melts at over 2,400°C and is far harder than nickel, which means the centre electrode can be made very fine, typically around 0.6mm against roughly 2.5mm on a standard plug. A finer electrode concentrates the spark and needs less voltage to jump the gap, so the coil has an easier job and the mixture lights more reliably.

What you actually notice: easier cold starts, a steadier idle, cleaner running at low revs on a fuel-injected bike, and fewer of the small misfires that make a tired engine feel rough. What you will not notice is a meaningful power increase. A spark plug does not add power to a healthy engine, it stops a healthy engine losing it. Anyone selling you an iridium plug on the promise of extra horsepower is overselling.

The honest case for iridium is that it holds its specification for far longer. A nickel electrode erodes, the gap widens, the coil works harder to bridge it, and the engine slowly gets worse in a way you stop noticing because it happens over months. Iridium delays all of that.

Iridium vs normal nickel spark plugs

	Nickel (standard)	Iridium
Centre electrode	Around 2.5mm	Around 0.6mm
Voltage needed to fire	Higher	Lower
Cold starting	Adequate	Noticeably better
Wear resistance	Erodes steadily	Holds its gap far longer
Typical service life	The interval in your manual	Commonly around double, but the manual still governs
Price	Low	Higher up front, cheaper per kilometre

How to read a spark plug code

An NGK part number is not random. Once you can read it you can tell at a glance whether a plug someone is selling you is even close to right.

Take CPR8EAIX-9:

• C and the letters before the number describe the physical plug: thread diameter, hex size and whether the insulator is projected.
• R means resistor. This one matters. A resistor plug suppresses the radio-frequency noise the ignition throws out, and a modern fuel-injected bike's ECU expects it. Fitting a non-resistor plug to an FI bike can cause genuine electrical gremlins. Every bike plug we sell is a resistor type.
• 8 is the heat range.
• E is the reach, meaning how far the threaded section extends into the head.
• IX marks it as NGK's Iridium IX line.
• -9 is the factory gap in tenths of a millimetre, so 0.9mm.

The practical takeaway: if the numbers and letters differ from the plug your bike specifies, it is not an upgrade, it is the wrong part. The CB350 is the clearest example in this guide: a CPR8EAIX-9 and a CPR6EAIX-9S are the same size and either will thread in, but only one of them is the heat range the factory chose.

Heat range, and why it matters more than brand

Heat range describes how quickly a plug sheds heat into the cylinder head. It has nothing to do with how hot the spark is, which is the most common misunderstanding.

On NGK plugs, a higher number means a colder plug. A CR8EIX runs colder than a CR7EIX. Be careful with cross-brand comparisons, because Denso numbers them the other way round. One step is worth roughly 70 to 100°C at the tip, so two steps is a meaningful difference rather than a rounding error.

Get it wrong in either direction and you have a problem. Too hot a plug and the tip can glow enough to ignite the mixture before the spark does, which is pre-ignition, and it destroys pistons. Too cold a plug and it never gets hot enough to burn off deposits, so it fouls, especially on a bike that does short city trips. The two failures are not equally bad, which is why fitting slightly colder is the common aftermarket habit, but neither is as good as fitting what the manufacturer specified.

This is why "the same plug but iridium" is the only safe upgrade. Match the heat range your manufacturer specified and change nothing else.

Gap, torque and fitting

1. Work on a cold engine. Aluminium heads and steel plug threads expand at different rates. Removing a plug from a hot head is how threads get pulled.
2. Leave the gap alone. Iridium plugs arrive pre-gapped, and the fine centre electrode is not built to be levered on with a feeler gauge. If you must check it, never apply force to the centre electrode itself.
3. Do not overtighten. If you have a torque wrench, use the figure in your service manual. If you do not, seat the plug finger-tight until the gasket makes contact, then turn roughly a further third of a turn for a 10mm or 12mm plug and about half a turn for a new 14mm gasket-type plug. Overtightening is far more common and far more expensive than undertightening.
4. Replace as a set on any bike with more than one plug, so all cylinders and positions are running the same condition.

When should you replace a spark plug?

Follow the interval in your owner's manual first, because that is what protects your warranty. Beyond the schedule, these are the signs a plug is finished:

• The engine is harder to start, especially first thing in the morning.
• Idle hunts or feels lumpy where it used to be steady.
• A stumble or flat spot when you crack the throttle open.
• Fuel consumption creeping up with no other explanation.
• On inspection: a rounded-off electrode, a widened gap, oily black wet fouling, or a chalky white tip.

Take the old plug out and look at it before you throw it away. It is the cheapest diagnostic tool you own, and its colour tells you whether the engine is running rich, lean or clean.

Iridium plugs and E20 petrol

Upgrade to iridium regardless of what is coming out of the pump. The case for a fine-wire iridium plug has nothing to do with fuel policy. It fires a stronger, more focused spark at a lower voltage, and it holds its gap for far longer than nickel. That is worth having on E20, on E10, on straight petrol, and on whatever the blending mandate does next. Fuel blends come and go. A plug that lights the mixture cleanly and keeps doing it is simply the better plug, and across the life of the engine it is the cheaper one too.

What E20 does is raise the stakes a little. Ethanol carries less energy per litre than petrol, shifts the mixture slightly leaner, and holds moisture. None of that is a crisis, but it does mean a tired spark shows up as rough running sooner than it would have on the older fuel. A plug that was merely getting old on E10 can feel properly past it on E20.

So the honest position: iridium is not a cure for ethanol, and it will not fix the other things E20 touches, such as ageing fuel lines or rubber components in the fuel system. What it does is take ignition off the list of things that could be making your bike run badly, and keep it off that list for years. If your bike has been running differently since the fuel changed, read our guide to E20 petrol in India and how to protect your engine, because the plug is only one part of that picture.

Iridium IX, Laser Iridium and Double Iridium

• NGK Iridium IX. Iridium centre electrode, nickel ground electrode. NGK's performance replacement line and the one most bikes in this guide use.
• NGK Laser Iridium. Iridium centre electrode plus a platinum pad welded to the ground electrode, so both wear surfaces are protected. Longer life again, and it is often the original factory fitment on bikes like the Honda CBR250R.
• NGage Double Iridium. Precious-metal tip on both electrodes, made in Japan, sold as model-specific part numbers rather than a broad range.

All three are a real upgrade over nickel. The difference between them is how long they hold their edge, not how well they fire on day one.

What is the best spark plug for Royal Enfield?

Fit the iridium plug specified for your engine platform, not for the model name. Royal Enfield has used four quite different engines recently and they do not share plugs.

• J-platform 350 (Meteor, Reborn Classic, Hunter, Bullet Reborn, Goan Classic): NGage DH7RTII-8, ₹899.
• UCE twin-spark 350 and 500 (older Thunderbird, Classic, Bullet, Electra): NGK BPR5EIX plus CPR6EAIX-9S, ₹1,730 for the pair. Single-plug UCE models, including the BS6 Classic 350 and Bullet 350 and the Continental GT 535, take the BPR5EIX on its own at ₹865.
• Himalayan 411 and Scram 411: NGK CR7EIX at ₹865 or NGage B8RII-8 at ₹899.
• Interceptor 650, Continental GT 650, Super Meteor 650: the same choice, two of them.
• Shotgun 650, Bear 650, Classic 650, Bullet 650: NGage B8RII-8 at ₹899, two of them. NGK does not list the CR7EIX against these four, so we point you at the NGage plug, which NGage lists for the Shotgun, Bear and Classic 650. The Bullet 650 shares the Classic 650's 648cc engine, so it takes the same plug.
• Himalayan 450 and Guerrilla 450: NGage BN8RTIIA-9 at ₹899, or the complete ignition kit at ₹4,989.

How to choose the right spark plug (fitment guidance)

1. Identify the engine, not the model name. Manufacturers reuse names across completely different engines. The Classic 350 and the Himalayan are both good examples.
2. Match the heat range exactly. Same number as the factory plug. This is not the place to experiment.
3. Count your plugs and check whether the positions take different part numbers.
4. Check it is a resistor type if your bike is fuel injected.
5. Leave the gap as supplied and torque it properly on a cold engine.

If you are not sure which plug your bike needs, send us your model, year and registration and our team is happy to offer fitment guidance before you order.

Frequently asked questions

Which is the best spark plug brand for bikes?

NGK and NGage are the two best spark plug brands for bikes in India. NGK Iridium IX is the original-equipment standard and has by far the widest fitment range, starting at ₹515. NGage Double Iridium carries a precious-metal tip on both electrodes and is made in Japan, at ₹899 across the range. For most riders the deciding factor is simply which brand makes the correct part number for your engine.

Are iridium spark plugs worth it?

Yes, for most modern bikes. An iridium plug has a centre electrode of roughly 0.6mm against about 2.5mm on a standard nickel plug, so it fires a more concentrated spark at a lower voltage. That gives easier cold starts, a steadier idle, more consistent running on fuel-injected engines and a much longer service life. It will not add meaningful power, so treat it as insurance for clean ignition rather than a performance part.

What is the difference between iridium and normal spark plugs?

An iridium plug has a very fine, very hard centre electrode that fires a stronger, more focused spark and resists erosion, so it holds its gap far longer. A normal nickel plug has an electrode around four times thicker, costs less and wears measurably faster. Iridium typically runs to around double the service life of nickel, though your owner's manual interval still governs.

Which spark plug does the Honda CB350 take?

The Honda CB350, H'ness CB350, CB350RS and CB350C all leave the factory with an NGK MR6K-9, Honda part 31916-K0Z-901, at heat range 6. The iridium equivalent at that same heat range is the NGK CPR6EAIX-9S, and all four bikes take one plug. You will also see the CPR8EAIX-9 widely sold for the CB350. It is the same 10mm thread, 19mm reach and 16mm hex so it does fit, but it is heat range 8, two steps colder than the factory plug. Both work; the CPR6EAIX-9S is the one that matches what Honda specified.

What is the best spark plug for Royal Enfield?

It depends on the engine platform, not the model name. The J-platform 350 (Meteor, Reborn Classic, Hunter, Bullet) takes an NGage DH7RTII-8. The older UCE twin-spark 350 and 500 takes an NGK BPR5EIX together with a CPR6EAIX-9S. The Himalayan 411, Interceptor 650, Continental GT 650 and Super Meteor 650 take an NGK CR7EIX or an NGage B8RII-8, one for the Himalayan and two for each twin. The newer Shotgun 650, Bear 650, Classic 650 and Bullet 650 take the NGage B8RII-8, since NGK does not list the CR7EIX against them. The Himalayan 450 and Guerrilla 450 take an NGage BN8RTIIA-9.

How long do iridium spark plugs last?

Iridium plugs commonly run to around double the interval of a standard nickel plug because the hard, fine electrode resists erosion and holds its gap. Always follow the replacement interval in your owner's manual, since that is what protects your warranty, and replace with the exact part number specified for your bike.

How many spark plugs does my bike need?

Most single-cylinder bikes take one. Parallel twins such as the Royal Enfield 650s, Kawasaki Ninja 300 and Yamaha R3 take two. Royal Enfield's UCE twin-spark engine takes two plugs of different part numbers. Bajaj Triple Spark engines, including the Pulsar NS200, RS200 and Dominar, take three: one centre plug and two side plugs, which are different parts and are not interchangeable.

Does a higher heat range number mean a hotter plug?

No, and this catches people out. On NGK plugs a higher number means a colder plug, so a CR8EIX runs colder than a CR7EIX. Denso numbers its plugs the opposite way. Always fit the heat range your manufacturer specified, because too hot a plug risks pre-ignition and too cold a plug fouls up on short city trips.

Do I need to gap an iridium spark plug?

Usually not. Iridium plugs are supplied pre-gapped for the application, and the trailing number in the part code, such as the 9 in CPR8EAIX-9, is the gap in tenths of a millimetre. The fine centre electrode is not designed to be bent or levered against, so if you check the gap, never apply force to the centre electrode.

Are iridium spark plugs better for E20 petrol?

Yes, and the case for iridium does not depend on the fuel at all. An iridium plug fires a stronger spark at a lower voltage and holds its gap far longer than nickel, which is worth having on E20, on E10, or on any blend the mandate moves to next. E20 simply raises the stakes: ethanol runs slightly leaner and carries less energy per litre, so a tired spark shows up as rough running sooner than it used to. Iridium is not a cure for ethanol and will not fix ageing fuel lines, but it takes ignition off the list of possible problems and keeps it off for years, whatever the pump is serving.
