ok so go for the 4-2-1 and do or don't get ceramic? i was looking around on ebay and this guy had a aem short ram for sell(for $50) and he said you can buy an aftermarket cover for the air filter so it won't suck in hot engine bay air and just get some cheap pipe and make your own cai with no chance of suckin up water. anyways would the ceramic heat up the engine bay more than a stainless steel or would it keep it a little cooler. :thinking:
