Sprint Filter P08 Air Filter for WorldSBK Racing – MV Agusta F4RR (2013–2015) R189S-SBK

The WorldSBK element for the F4RR comes in three versions, and choosing between them is the only real decision on this listing. R189S-SBK carries the P08 cloth at 80 µm and 5,050 l/m²/sec. A second part number carries the F1-85 cloth at 85 µm and 15,000. A third carries the water-resistant P037 at 37 µm and 4,500. Read down that list and the tidy assumption that finer always means better comes apart twice.

Key Features

• P08 medium in the WorldSBK frame: 80 microns, 5,050 l/m²/sec
• Dry from new and dry after every clean — there is no oil in this system at any point
• Measured retention of 93.13 % of 100-micron particles, against 76.42 % for four-layer oiled cotton
• Roughly twice the filtering area of other performance filters
• Takes the standard housing as it is: no modification and no remapping
• Washable and reusable for the life of the machine, two years of warranty

Where the ladder breaks

Descending the range, each finer weave buys retention and pays for it in flow: P037 at 37 µm gives 4,500 l/m²/sec, P14 at 14 µm gives 1,800, T12 at 7 µm gives 560. That is a trade rather than a ranking, and a T12 is not a superior filter to a P08 — it is made for different air. The break comes at the top of the list. The F1-85 is the coarser cloth at 85 µm, yet its measured retention is 95.22 % against the P08's 93.13 %, while flowing three times as much. An aperture in microns describes geometry; a retention percentage describes an outcome, and the two are not obliged to move together.

Which one belongs in an F4RR

The P08 version is where to start, and for most owners it is where the question also ends. The F1-85 is bought for sustained wide-open work — the kind that is held rather than sampled — and asks a good deal more money for capacity a road-ridden bike never spends. The P037 answers weather rather than speed, a water-resistant cloth for machines used in the wet. None of the three will make the engine noticeably stronger, so the choice is about the conditions the element has to live in, not about a line on a graph.

Care and cleaning

Regeneration here is mechanical, not chemical. Compressed air on the clean face of R189S-SBK, blown outward, returns the cloth to something close to its original state, and most of the time that is the entire procedure. A wash deals with whatever survives a dirty spell: a mild detergent in warm water, then a rinse until the run-off is clean. After that, leave it alone in open air until it is dry through. Heat guns, radiators and flames are all off the list, because polyester is the part heat attacks. Nothing is applied to the medium before it goes back in. Maintenance sheet: Downloads tab.

Fitment & Compatibility

For the airbox of the MV Agusta F4RR 1000 of 2013 to 2015. Eight machines take the identical element — the F4 and F4R from 2013, the F4RC and F4RC LH running to 2026, and the Brutale Oro, Brutale RR and Rush among the naked models.
