Now that more and more manufacturer's are getting up to speed with the 450R, I was wondering what air filter kits are available. I am looking for a nice aluminum mounting ring and the largest, free flowing foam air filter out there. What kind of pro flow kits are available? I like UNI filters, but want a nice kit to go with it. Also open to other foamys though. What is everybody else using? I plan on running the foamy with a EHS lid kit I think, any recommendations?
