"High Efficiency" is an air filter that offers excellent performance thanks to a greater air flow than the original filter, and also offers greater protection to the engine.


This filter is studied in detail to distribute oxygen equally to all cylinders, in fact in the upper part there is an AIR SPLITTER that facilitates the flow of air.

MWR air filters are handmade in Holland with high quality materials and are very long lasting.



General characteristics of MWR filters:

This filter is perfectly interchangeable with the original, does not require modifications for correct assembly.
