Sprint Filter CM274T12 Air Filter for Royal Enfield Himalayan 450, Extreme Conditions

Sprint Filter CM274T12 Air Filter for Royal Enfield Himalayan 450

The Himalayan 450 is the one bike in this range that genuinely goes where the dust is. The Sprint Filter CM274T12 is Sprint's finest media, built for exactly that. It drops straight into the factory airbox and replaces the paper element for good.

A dry filter, not an oiled one

Almost every performance air filter sold in India is oiled cotton gauze. It works, but it comes with a routine: strip it, wash it, dry it completely, re-oil it evenly, and hope you did not over-oil it.

Sprint Filter's T12 media is different. It is a dry filter: to service it you take it out, blow it through with compressed air, and put it back. No cleaning solvents, no oil, no drying time, and no risk of oil residue migrating downstream into the intake tract of a fuel-injected engine.

The numbers Sprint publishes

Sprint Filter is unusually specific about its media, which makes it possible to compare grades honestly rather than by adjective:

• Filtration: traps debris down to 7 microns
• Airflow: 560 litres per square metre per second
• Media: special non-woven polyester fabric
• Servicing: dry, compressed air only

Which Sprint grade is right for you

Sprint make three media grades, and the trade-off between airflow and filtration is real. More airflow means a coarser weave:

• P08 — 80 micron, 5,050 l/m²/sec. Road and track use on sealed surfaces.
• P14 — 14 micron, 1,800 l/m²/sec. Finer filtration for genuinely dusty routes and high-mileage daily use.
• T12 (this filter) — 7 micron, 560 l/m²/sec. Off-road, gravel and desert conditions.

This is the trade-off worth understanding before you buy. The T12 filters more finely than anything else Sprint make, and it flows the least air of the three. If your Himalayan spends most of its life on tarmac, the CM274S in P08 is the better choice. If it genuinely sees gravel, sand and trail dust, this is the one.

Built to outlast the service schedule

Polyester is a manmade fibre and, looked after properly, shows no meaningful loss of structure or filtering performance over time. Where a paper element is a consumable you buy again at every service, the CM274T12 is a component you fit once and clean periodically. Over the life of the motorcycle that changes the arithmetic considerably.

The element is manufactured in Italy by Sprint Filter, who supply filters into World Superbike and Grand Prix paddocks. This is the same media technology, in a road-legal replacement size.

Fitment guidance

Sprint catalogue the CM274T12 for:

• Royal Enfield Himalayan 450 (2024 onwards)

Sprint list the T12 grade for the Himalayan 450 only. The Guerrilla 450 shares the same 452cc engine, and Sprint catalogue the P08 grade (CM274S) for both bikes. If you ride a Guerrilla and want the T12, talk to us first and we will confirm with Sprint rather than guess.

It is a drop-in replacement for the factory element and requires no modification to the airbox, no trimming and no additional hardware. If you are unsure whether this is the correct part for your bike or your model year, send us your registration details and we will help you check before you order.
