Stick with oem, they will provide the best performance on a nearly stock or stock engine. Many of the advertised plugs you see actually hurt performance or make no difference. If you happened to have a lot of mods you can sometimes benefit from a colder heat range or gap changes.

I have a k&n cold air, throttle body spacer,banks power programmer and a custom exhaust... should i still go with the oem?
