Sprint Filter P08 Air Filter for Road & Track – Royal Enfield Bullet Trials 500 EFI (2011–2026) CM195S

Two Bullets sit on this part number with identical entries: the same 500 cm³, the same 2011 to 2026 window, the same airbox. Whatever separates a Trials from a B5 on the road, the intake is not part of it — which makes the ordering decision simpler than it looks. You are not picking a filter for a model, you are picking a medium for a housing, and the housing is common property. The Sprint Filter CM195S is the standard rung of that choice: dry woven polyester, cut for the series box, washable.

Key Features

• Dry polyester weave, one layer, never oiled — nothing to over-apply and nothing to migrate downstream
• 80 µm filtration paired with a rated 5,050 l/m²/sec of flow
• The ø 22 micron specification describes the thread of the weave, not the openings between threads
• About double the filter area of other performance panels, inside the unmodified airbox
• Straight swap for the factory panel: same frame, same sealing face, same fixings
• Cleaned and refitted rather than replaced, with a two-year warranty from purchase

One housing, one decision

Sprint Filter lists three media against this box and only three: the 14 µm P14, this 80 µm weave and an 85 µm racing cloth. No water-repellent medium is offered for this housing and no off-road one either, so the ladder is short and the standard rung sits in the middle of it. That is not a ranking. Finer cloth holds more and passes less air; coarser cloth does the reverse. The P08 is the only rung with no condition attached to its name, which is why it is the one specified for road and track use.

What changes at the handlebar

Very little, and that is the honest answer: a drop-in element will not make a standard machine noticeably quicker, whatever the model on the tank. The gain is a lower and, across a service interval, steadier resistance in front of the throttle body, plus a part that never appears on a shopping list again. Fitting is a hand-tool job with no consequences for fuelling — the engine management sees the intake it always had.

Care and cleaning

Compressed air does most of the work. Hold the line on the clean side of the CM195S and drive the dirt back out through the face it arrived on, never from the dirty side inwards. When the deposit is oily rather than dusty, warm water with a mild washing-up liquid will lift it; rinse thoroughly afterwards. Then let it dry fully in moving air, well away from any heat source, and put it back untreated. Full instructions sit under Downloads.
