enough for 1 step colder plugs?

tobylazur · 03-24-2008, 01:10 PM

I was reading the spark plug FAQ, and it suggested colder plugs for every 75-100hp you increase. so here's my question:

right now I have an AP stg. 2 tune, with turbo back exhaust, and a shortram intake. Do I have enough power over stock to warrant a step colder plugs?

Thanks for the help guys.

you could go either way. personally if it were me, i'd run the stock plugs with that setup.

feel a difference??

Are you sure it wasn't the turbo you were feeling?

And no, I wouldn't do it on a stg 2. You can, but I don't see the point.

it would have made sense if you put the colder plugs in and THEN went and got the tune... not after the fact.

I'm not sure that a vf39 mod in a car constitutes stage 4 either, especially untuned.
