What is the best way to mod the airbox? I seen where some guy has some rubber grouments for sale for $20 bucks,which i think is a little bit high on the price.
that's a foam filter just like the stock one. light foam (large open holes) on the outside with dense foam (small, fine holes) on the inside. the stock filter does not sepperate... it is glued together at the seems. some foam filters come apart. although, i don't see why it is necessary. other dual stage foam filters... UNI, Curtis Sparks, White Bros, etc. none of those come apart either. the pro design pro flow system does.Originally posted by trx450Rrider@Jul 8 2004, 05:56 PM
