A quick question. Is it worth to buy NGK spark plugs and LET spacers? OR more so a mod you add when u run high boost? In response to how i drive my car, This car is my daily driver, i dont know enough about modding so im not keen to be forking out $ on problems and issues. I will be voiding my warranty so i would like to be as reliable as possible. I dont do track racing, all i want is extra noticable power to have fun with. Thanks for all your suggestions.
