I did a search and there are so many opinions on plugs. Ok, here it goes....
I have a 2002 WRX. Stock plugs in it. Mods: complete Top Speed exhaust system (header, uppipe, downpipe, cat back) and no cats, all a 3" system. K&N with the stock intake except it does have a silencer delete elbow. Samco Intercooler hoses. Stock turbo and intercooler. EBC, Apex-I ACV-R set @ 16.25 psi. Turbo XS type H-RFL BOV.
So with these mods what is the best plug for it performance wise that last long cuz it will be a PITA to install. What gap do you set it. My car has almost 46,000 on it so it is prolly due for a plug. It also sometimes starts weak when I turn the key. Any help is appriciated much. Thanks guys!!!
