I was wondering which air filter would be the best for the 650. Twin Air or K & N, or maybe something else? i do plan on an exhaust mod in the near future.
Thanks for posting!

 

Twin-air would probably be the best for off-road conditions common of 4x4 quads...the K&N allows more air passage which in turn creates power, however it will typically pass more dirt/sand through to your motor.

BRAAAAP

 

Thier Both Good, I have K&N's with outerwear's and run with open air boxes, havent had any problem's so far

 

I have a K&N on my Kodiak with an Outerwears on it. I elected to put a Twin air on the P650 for fit reasons. I heard the K&N for the 2002 models dont seal as good as they should. Plus, the Twin air is around $15 cheaper. "But, that isnt why I bought it"
