MWR High Efficiency Air Filter for the Aprilia RS / Tuono 125 4T and RX/SX 125 4T (2021+)

Our new and improved HE air filter can now be installed without the original filter holder. This new design creates a better seal with the airbox and increases the airflow between the filter frame and splitter-plate which equates to more power for your bike (average gains of the filter alone for most bikes, before any tuning or exhaust is 4-6 HP)!

The wide foam material offers barely any measurable air resistance and the surface area is as large as possible so more air gets to your engine! Also the filters are impregnated with MWR's special oil, so that even the smallest dust particles are stopped.

Filter replaces the original airbox cover to create bigger airbox opening for more airflow / power

Remove original cover / filter & filtercage , install MWR filter instead (see pictures)

Fits with original bolts

Splitter plate protects filter from direct water contact

Top teams and riders in MotoGP, Moto2, WSBK, WSS, BSB, MOTO AMERICA, and other championships choose MWR Air Filters for a reason!

And yes, the oil and filter materials are naturally non-flammable.
