What is RM Cash
Ron in OR
I have used K&N Filters for years on everything form boats to motorcycles and have never been disappointed.
Dan in PA
Fits my yz 450 air box good. Use filter grease!
Remove back fire screen and secondary filter when using this.
More surface area and better filtration. K&N!
Lasts a lifetime, literally
Always amazed at how much crap this releases. Aerosol oil is easy to use. Dont be afraid to use it!
Necessary for a newer yz450's air box. Works good and seals the filter well.
Dewey in KS
I run these in my other bikes, so I figured I'd upgrade my supermoto. I'm glad I did. She's got that K and N whistle now. It fits great!
Brendan in PA
Pretty easy to use, removes the old oil nicely. One bottle should last a long time.
