hey just had an idea my brother has this intake for his celica. has had it for quite some time and its still in the box so i think im going to take it and use the air filter now ive seen some pvc intakes and they seem to work well. they dont get hot on the inside from what i hear. i think i might do this to save some money. what im wondering is if any of you guys have had bad experiences with pvc intakes or what?
