The Instructions included were helpful and the billet plate provides a much nicer way to clamp the filter on. My only complaint was in order to use the K&N filter with it you must grind down or cut out part of the stock plastic airbox where the screw goes for the stock filter (this was on a 2007 Suzuki LTR 450, other models may not need airbox modification). You must do this in order to make it fit. It would be nice if you didn't have to do the modification, but it seals very well and is much better than the stock intake set-up.

I put the filter on a crf250r and it really didn't help in any off the line but you can really tell the difference in 4th and 5th gear.

Easier to install then explained. Great product overall though. No complaints and fit my KFX450R perfect.

I have several buddies that have drilled out there stock lid and have flooded the airbox as a result. The K&N lid fixes that problem and allows more air in.
