Stock St205 raising boost to 14psi Options

[cax_11]

If I raise boost to 14psi,do you recommend i get colder plugs??

if the only mod your doing is raising a few psi your not going to get a truck load more power so based on that alone ide stay stock.

BUT if your planning on further mods down the track...and lets face it who isnt, then going a step colder now wont hurt (if your getting new ones anyway).

To give you an idea im making around 400 awhp and im just using copper, grade 7 heat range plugs. No detonation here. Change them every 5000kms, but at only a couple of $$ each it doesnt matter.

I advise against irridums. They are fine for stock or near stock, but cant/shouldnt be gapped and are expensive to change frequently.
