Here is what we did and it has worked perfect. The most restrictive part of the filter is the cage. It really depends if you had some motorwork that would require more flow. We used Moose filters with EHS lid and a modified cage and it dyno'd great.

what about running with out the cage?? i took off my stocker to clean it... it was nasty an real sticky do this sound right?? jus clean it woth warm water n detergant??

I wouldn't. It will suck the filter together and really prevent air flow. When we cut it there was no issue and it increased our airfow a good bit.
