Air filters

im runnin pink wire cut lid off moto works slip on, should i use a K&N or just stay with the stock filter?

A K&N picked up quite a bit for me. Find a quad that is fairly close in a race then install it and walk away from them.

i run the stock filter and the pink wire cut with a hmf pipe and it runs great. i keep the lid on now that i got a aftermarket exhaust,it seems to run better...im gonna get a k&n but the stock is wrkin just fine for now

i´m running motoworks full exhaust with the fmi and pink wire cut.
first started with the stock filter and then changed to k&n. always with the airbox lid off.

think there is a little more power with the k&n.

alright guess im gona have to slap on my k&n, also another thing has anyone hooked up a fuel/air gauge yet? and where should i mount it?
