13 bucks is going to HURT your perfomance man, i am telling you with all that extra hot air your sucking through the blower it is nOT good, take it off and run a papaer filter again, it is better than that. As far as the coolant bottle goes… the FW wouldn’t even come close to hitting the bottle. Oil leak prob coming form you front cover. And for around 100-200 bucks your DD GTP could be running better times than your LT1:doh:
