how much more performance willi get with a k&n air filter kit, and prefilter, and k&n jet kit. i also have the aaen megaphone muffler. this is for my 2001 trailboss 325. thanks

 

Not much at all. But at least you can reuse the filter.

 

not much..but i guess every little bit counts.

 

You will not notice much at all.To get the most performance change get a pipe to go with your megaphone silencer!

 

I have the aaen exhaust, K&N filter, jetted, and the RCR green spring. These really helped my quad out. It will actualy pull and carry a wheelie now.

Being a 4 stroke a bigger pipe would only help if the motor was worked up a little, big bore, cam, porting.

 

Dont waste yor money on a K&N jet kit just use the jets from your dealer they are just as good and cheaper.
