That is the setting in which a washable panel stops being a maintenance detail and turns into a convenience. Every paddock has compressed air in it somewhere. Twenty minutes between sessions is enough to lift the element out, blow it through and put it back, which is not an option a paper panel offers on any day of the year.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWoven polyester used dry — nothing oiled from new, nothing treated after it has been washed\u003c\/li\u003e\n\u003cli\u003e80 µm apertures and a rated 5,050 l\/m²\/sec of flow, the P08 specification for road and track\u003c\/li\u003e\n\u003cli\u003eThreads from ø 22 microns; filtration happens between them, at a figure quoted separately\u003c\/li\u003e\n\u003cli\u003eApproximately twice the filtering surface of other performance elements in the original frame\u003c\/li\u003e\n\u003cli\u003eFits the standard airbox in place of the paper panel, with no modification and no remap\u003c\/li\u003e\n\u003cli\u003eCleaned and refitted indefinitely, warranted for two years from the date it was bought\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eServicing between sessions\u003c\/h2\u003e\u003cp\u003eA dry circuit is not clean air. Rubber leaves the tyres, dust leaves the brakes, and a full grid keeps all of it moving at the height an airbox draws from. Over a long day the element takes on more than a week of ordinary road riding would give it, and with paper there are only two answers: leave it where it is, or have bought a spare in advance. The PM109S turns that into a five-minute job using equipment already on site, and the machine goes out for the next session at the intake resistance it started the morning with.\u003c\/p\u003e\u003ch2\u003eThe racing medium, and who it is for\u003c\/h2\u003e\u003cp\u003eThis is also the only R nineT for which Sprint Filter catalogues a racing medium in the same housing — the P08 F1-85, rated at 15,000 l\/m²\/sec, roughly three times the flow of the P08 through a slightly coarser 85 µm weave. A flow rating is a ceiling and not a delivery, and a road-registered boxer never comes close to asking for that ceiling; the F1-85 is there for engines that have been opened up and for machines that live on a circuit. Everywhere else the P08 is the right specification. It should be said plainly that neither of them makes a standard Racer faster: an element in a standard box is not a power part.\u003c\/p\u003e\u003ch2\u003eCare and cleaning\u003c\/h2\u003e\u003cp\u003eBlow the element through with an air line from its clean face outward and the normal service is finished. Where a track day or a wet ride home has left something the air will not move, hand-warm water and a mild detergent will do it, with a rinse until the water comes away clear. It must then dry completely in moving air, well away from heat and flame, and it is refitted dry with no dressing of any kind. The maintenance sheet is in the Downloads tab.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eMade for the BMW R nineT Racer built from 2017 to 2020, replacing the standard element in the unmodified airbox.
