new headers: Headers will give more performance, but do your homework on them
platinum spark plugs: NEVER in these cars! The factory plugs are Iridium. Either stick with the Iridium, or put in a cheaper Autolite 605 copper plug.
so a k&n filter WILL actually improve performance? by how much? (at least 5hp?)
and i dont understand what u said about the exaust. im sorry, im just starting to get in to cars now that i have a friend with a celica GT (from between 00-05, 4cylender he has new intake, exaust, headers) and a friend with a 05 350Z (stock, v6)and i want to destroy both of them, lol
so what are the cheapest things i can do to my car to add horsepower with out damaging the car? i assume k&n filter ($45) is #1.
i just want to be faster than a 2005 350Z :P
but if thats not possible on the cheap, than so be it. i can still beat him (he cant shift, lol). just what should i buy that is cheap and will help performance? would those copper plugs benefit me? my car's mileage is only in the 40,000s (hard to belive, but true) so everythings pretty new (still got the new car smell, not even kidding!)
