If you want to get more power out of your motor, you need to get more air and fuel through it, plain and simple. Shop the best dirt bike air filter and intake upgrade parts on the web at RevZilla.com. High-flow air filters for dirt bikes should be your first stop on the quest for more power. Coupled with a good pipe and the right jet kit (if you have a carburetor) or fuel tuner (if you have fuel injection), an aftermarket air filter is going to let your motor breathe more freely while maintaining great protection against sand, dust, dirt and debris getting into your carb or throttle body and motor, yielding more power while preventing labor-intensive damage to your top end. RevZilla stocks all the top brand dirt bike air filters, from hassle-free pre-oiled foam filters to paper elements, in both universal and exact-fit applications to your specific bike. And if you ride a 2 stroke with a reed valve setup, you can find replacement high performance reeds, gaskets, and entire rad valve kits to ensure your reed valve is in race-ready shape to maximize compression and widen your powerband across the whole rev range.
