Looking for a small 4" air cleaner for 600-650whp. I do run a pretty big KN now, but want to reroute the air filter and need a smaller one. It must have 4" inlet.
Any recommandations?

Thanks

I am thinking of running a 9'' or 12'' k&n on my setup, is that what ur currently running? do u have any pics of ur setup?
Thanks

I've since stop using the Perrin foam filter as I got tired of the oiled filter. That Buschur piece looks like it would do the trick though.

For reference I am currently using a the RE-0870 and removing it netted no gains. The intake tube was put out of the hot air zone behind the radiator (dont have a fan there anyway).
