hey ppl, 2day i cleaned my air filter as it was the ast time i checked it in like more than a year, and it was dirty, so i cleaned it abit (not 100%) and i reved the car abit and i swear it sounded like a different car, i tried driving it abit too and i could feel that it would go abit easier too, like times when it would have stalled b4 and now it wont, so im pretty impressed Since thats a stock air filter i was thinking of getting a KnN Air Filter, do you think it will make any difference at all? in what ways will it make a difference, and how much in australian dollars would one cost? thanks heaps people Merry Christmas!
