Just read on the depot that you can bolt on a PI intake mannifold to a NON PI head and it is good for rediculous gains. IDK if anyone else has seen this but i think its big. Being one of those kids that just cant dish out the cash for the heads, this mod is very realistic. this guy got almost 30hp from this mod spent only about $200 on the manifold and other minor part needed. A CAI will run you $200 and you are lucky if you gain 4 or 5hp. Im going to wait on it a little bit and give this guy enough time to see if any problem develop, but im so psycked about this!
