i woudnt even worry about it...ide put the stock unit back in. the C&L will give you 0 hp, unless you actually need more airflow, lets say like you had a blower on your car.

 

The stock unit over the MAF? Why?

 

an aftermarket maf is a waste of money. you gain 0 hp, no matter what people tell you. the only way to pick up hp is if your engine needs more air ie. blower, stroked

 

that's partialy true that why exhaust is the first mod and the maf is needed because it is the restriction going biger than 73 is not needed becuase you T/B will the the next restriction....most people have a positive hp gain on this mod AFTER exhaust has been addressed
