The place racing cai is probably the best bang for the buck, you can pick one up for around 187 from rollhardperformance.com. I myself made my own as well as my boy nismoser. We had 3 inch pipe bent from meinekee that would go from the maf into the fender wall, at the end a K&N type cone filter that sits in the fender, just like a place racing or aem.....i deftately feel an improvement over the warm air intake i had before with just the cone on the end of the maf. The car pulls harder from about 3500 on, it feels great, and all in all it only cost us about 40 bucks a piece with the filter, adapter andpiping.
