What is RM Cash
Matt in OR
Easy to use and does a great job at collecting dust on my K&N filter.
PAUL in VA
I change my filter every other oil change (10hrs) and my YZ450 went 180hrs with nothing other then a valve shim. I don't trust anything else but K&M.
Jack in GA
Fits like OEM but with its cleanable element and adding a pre filter cover, this is gonna last many years more. That and the percieved throttle response make it well worth it
ALAN in PA
Best lid on the market. You will hardly ever have to clean your air filter because the lid catches all of the dust .
Dan in PA
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.
