The maintenance or replacement of the air filter is as important as regular lubrication of the chain or oil change. Clogged or dirty filters increase the fuel consumption noticeably!
Hiflo's air filters have been specially developed for modern "high performance" engines and adapted to the original air filter box. The filters are a direct replacement for the OE filter. There is no need to change any settings.
For the production of the filters only high-quality materials are used.
