NGK's Iridium MAX construction: a fine-wire iridium centre electrode paired with a platinum chip on the ground electrode. Built to outlast a conventional plug several times over. The fine wire concentrates the spark into a smaller, sharper discharge. In everyday driving that shows up as easier cold starts, a steadier idle and cleaner combustion. And because iridium barely erodes, the gap stays where the factory set it instead of drifting wider over the miles. Direct fit. No tuning changes, no adapters, nothing to set up.

Message us with your model and we will point you to the right part. Running CNG? On a CNG car this is the better plug, not a compromise. Most of the cars above are common CNG conversions, and gas asks different things of a spark plug than petrol does. All four differences point the same way here. CNG runs hotter. There is no liquid fuel evaporating to cool the intake charge, so combustion temperatures climb. This plug is heat range 7, one step colder than the standard plug, which is the direction a gas engine wants. CNG is harder to light. It needs more ignition voltage than petrol. The fine iridium wire concentrates the spark and fires at lower voltage, so it works with the gas rather than against it. CNG wears electrodes faster. Gas is harder on a plug than petrol is. Iridium barely erodes, which is exactly where it pays for itself. On CNG an ordinary plug is something you replace often. CNG burns clean. Almost no carbon, so the colder heat range carries no fouling penalty on a gas car. Fit them as supplied. It is still worth having the plugs checked slightly earlier than on a petrol-only car, simply because gas is harder on them.

These are among the most CNG-converted cars in India, and this is the plug for them on gas as much as on petrol. NGK lists no separate CNG part, and the heat range here is the same 7 as the standard plug, so it is a straight replacement either way. Where iridium earns its keep on gas is different from petrol: CNG needs more voltage to ignite. The 0.6mm fine wire concentrates the spark and fires at lower voltage, which counts for most on an older car whose coil and leads are no longer new. CNG wears electrodes faster. Gas is harder on a plug than petrol is, and iridium barely erodes. On a CNG car a conventional plug is something you replace often, and that is the cost this removes. Fit as supplied. Have the plugs checked earlier than you would on a petrol-only car, since gas is harder on them. And if the car has become hard to start on gas, worn plugs are the first thing to rule out.
