I desert raced dirt bikes for 15 years and am on my 2nd jeep and second ATV and I have always used K&N in all of my cars,trucks and toys. More power (maybe 5 but you can't tell the difference but it sounds great when you punch it)) better milage 1/2 MPG.
The reason that I am writing this thread is to let people know that my K&N's have never let debri in the intakes of any my veichles ever and they have been thrashed in powder and sand and never have let me down.
I started using them because of there off road protection and I got tired of constantly changeing paper filters. Dirt bikes come with foam filters that restrict air and K&N is the first mod we make out here.
No, I do not work for K&N
