Hey guys how does a throtyle body give you more hp..I now a stock one on 3rd gen camaro are 52mm and you can buy a 58 mm but I just dont under stand. Why is a 58mm better the a 52mm...
And on intake runners I am looking to get a set of slp runners.. I have been looking at some and they say that they add more hp to, how do they add hp and all..
