I always put a k&n in any vehicle that I buy. I bought this filter for my 1986 Honda trx and boy, what a difference. I have so much more power now. Great

Bought for a 2003 Honda CRF230F. Easy install.

The replacement filter worked better than expected on my 2014 Honda CTX. It gave me an immediate noticeable difference to throttle response. I am very happy.
