[4g63maniak]

Hello there just having troubles with my stock plugs i dont know ifthey are worn out by mileage or maybe they flaked for raised boost and fuel, im replacing them and i want to know if i should go with stock or maybe go with any other type.

Thanks

7's are colder than the 6's
I think he didn't get this info

Maybe he read the first reply and seen 6's or 7's then posted and never came back? I really don't know .
