Against the standard element for the same airbox, PM213S F1-85 costs a little over three times as much, so the same outlay would cover three ordinary panels. That ratio is not a fault; it reflects a different weave made in smaller numbers for a different job. But it sets the bar this medium has to clear on an R12, and on a road-ridden R12 it does not. The honest recommendation is the standard weave; what follows explains what the extra would buy.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDry polyester weave at 85 microns, the openest of the three media here\u003c\/li\u003e\n\u003cli\u003eRated at 15,000 l\/m²\/sec against the standard element's 5,050\u003c\/li\u003e\n\u003cli\u003eHeld back 95.22 per cent of 100-micron particles in the maker's test\u003c\/li\u003e\n\u003cli\u003eUnoiled like every medium here, so nothing migrates downstream\u003c\/li\u003e\n\u003cli\u003eSame panel shape as the standard element, into the airbox unmodified\u003c\/li\u003e\n\u003cli\u003eCleaned and reused rather than replaced, with two years of warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat the same outlay buys instead\u003c\/h2\u003e\u003cp\u003eThree standard elements, near enough, which is a slightly absurd thing to own since one is built to last the life of the motorcycle. That is the point. The extra buys no durability, no material quality, no longer interval; all of that is already in the ordinary weave. It buys one property: a ceiling on flow around three times higher. By its own account Sprint Filter is the most used air filter in MotoGP and World Superbike, and this is the cloth that does that work — a manufacturer's claim about racing, not a measurement on a road bike.\u003c\/p\u003e\u003ch2\u003eTwo clocks running at different speeds\u003c\/h2\u003e\u003cp\u003eThe 85-micron aperture is open every second the engine runs. The 15,000 l\/m²\/sec is drawn on only when the engine is asking for everything, which on a road-ridden R12 is a fraction of a per cent of its hours. One side of the trade is continuous, the other occasional, and that asymmetry is the case against the racing weave. The medium is not poor — it held back more of the 100-micron test fraction than the standard cloth — but its advantage is idle almost all the time while its cost is not. In neither position does a filter make a standard machine perceptibly stronger.\u003c\/p\u003e\u003ch2\u003eCare and cleaning\u003c\/h2\u003e\u003cp\u003eAn open weave gives its load up readily, one genuine advantage of the PM213S F1-85. Compressed air on the clean face, blown outward, clears most of it in a minute; from the dirty side it would be pressed in. Water with a mild detergent handles what air leaves behind, rinsed until it runs clear. Drying is done by air and time alone: no heat gun, no oven, no flame, because heat ends these elements long before use does. Refit dry, with nothing applied. The maintenance sheet is in the Downloads tab.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eFor the BMW R12 of 2025 and 2026, into the series airbox with nothing modified. Three machines carry this number: the R12, the R12 nineT, and the R nineT of 2021 to 2024 whose housing both newer bikes inherited. The name alone will not order it: the 2014 to 2016 R nineT sits on a different number, and so does every R nineT Scrambler through to 2024. The Fitment tab lists all three with their year spans.\u003c\/p\u003e","brand":"Sprint Filter","offers":[{"title":"Default Title","offer_id":53532809691402,"sku":"PM213S F1-85","price":361800.0,"currency_code":"MWK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/PM213S-F1-85.png?v=1787206353","url":"https:\/\/inter-pace.com\/en-mw\/products\/sprint-filter-p08-f1-85-air-filter-bmw-r12-2025-2026","provider":"Inter-Pace","version":"1.0","type":"link"}
