I know the differences between the two, but I dont know which will produce the most power on my evo. I've read that other cars were getting more power with the cai but i also saw that it's different with each engine.

 

cold air will work but short ram is fine also. check out the engine/turbo section... there is a thread in there about this same comparison........

 

alright thanks a lot i wasnt sure where to post this.

 

yep no prob

here this should get you started
