Sprint Filter P08 Air Filter for Road & Track – Royal Enfield Scram 411 (2022–2023) CM199S

Royal Enfield sells the Scram 411 as a scrambler and the Himalayan as an adventure bike, and everything that separates the two sits where a rider can see it: wheel diameters, bars, screen, the rack over the tank, the seat. Not one of those differences lies upstream of the throttle body. The airbox is the same box in both machines, which is why a single part number, the CM199S, answers both, and why an air filter cannot really be a scrambler part or an adventure part. It belongs to a housing, not to a segment. Quote the code and the year on the registration document and the badge on the tank stops deciding anything.

Key Features

• Single-layer woven polyester, dry from the first mile to the last, rated 80 µm and 5,050 l/m²/sec
• Specified around the airbox, so the same element serves the Scram and the Himalayan alike
• About double the filtering surface of conventional performance elements in the same space
• Direct replacement for the series panel — no cutting, no relocation, no remapping
• Retention measured at 93.13 % of 100-micron particles, where four-layer oiled cotton reached 76.42 %
• Washable, reusable, designed to last the life of the motorcycle, two years of warranty

Segments are drawn outside the intake

Model families are separated by the parts a buyer looks at, and the industry keeps that separation in its brochures rather than in its air ducts. Here the two machines share an engine, a frame and a filter box, so the intake makes no distinction between them at all. This matters at the counter: searching by model name invites the wrong panel from a similar-looking bike, while the code and the years settle it in one step. It matters again second-hand, where the airbox tells the same story on either machine.

Choosing dry over oiled

The element arrives dry and stays dry, and that is a specification rather than a convenience. Nothing has to be dosed after a wash, so nothing can be over-dosed; no film sits upstream of the throttle body waiting to migrate onto a sensor; and a cleaned panel is finished when it is dry, not when a coating has been judged even. Set against that, what it will not do should be said plainly: a drop-in element does not make a standard motorcycle noticeably stronger. It keeps the intake resistance low and, more to the point, stable across the whole service interval.

Care and cleaning

Compressed air along the clean face of the CM199S, always blowing outwards, is the routine job and usually the whole of it. When air alone will not shift a film, tepid water with a mild detergent will, followed by rinsing until it runs clear. Drying is done by moving air at room temperature and by nothing else — heat rather than dust is what ends this material, so no heater, no gun, no flame. It goes back into the box dry, with nothing applied to it. The maintenance sheet is filed under Downloads.

Fitment & Compatibility

For the Royal Enfield Scram 411 built in 2022 and 2023. The Himalayan of 2021 to 2023 takes the same element, two machines in total on this number. The Fitment tab lists the years covered.
