first off, Welcome to our happy little corner of the net. There is a BIG fridge in the corner with just about anything you can think of in it...help yourself...of course only take what you can LEGALLY have. :{D
make yourself at home on one of the big fluffy couches, kick your shoes off, put your feet up on one of the tables....and take it easy.
oh...btw....every once in a while a food fight breaks out...so you may not want to wear nice clothes here.
Welcome!! :{D
as far as the performance gains with an intake...well from what WE have all seen...you will get just about the same no matter what brand you use.
as far as people having trouble with the Injen....the ONLY people that I have heard of having trouble of ANY kind are those with automatics trannies and 1.6L motors.....and some have had a rub problem with the master cylinder. other than that....they are great....look great, sound great, FIT great
