My question is this, on the dyno, I post 3-4 more HP with a KKM vs a stock airbox and K&N filter on a 98 SVT. Is this extra gain just as a result of the hood being open? I mean once the hood is closed and the temps go up a bit, is the stock airbox going to far outperform a KKM ?
I know this is beaten to death but I need users opinions on it. Logic would tell me not to worry about the dyno...
