Do a search, there are loads of threads and opinions and no definitive answer.

you need to run cooler plugs if you are upping the boost

a well chosen plug should have the ability to not foul up with carbon and deliver the spark with out running too cool, causing missfires and wet plugs

i have gone 2 grades cooler Champion N7y as opposed to N9Y and everthings fine

iam running 12 psi of boost at the moment through a good intercooler

hope this helps

Me to ! Never had any probs on these, 16-17psi or so.
My friend Mike uses the 6's and runs some "interesting" boost levels, strangely he's never had any problems around the 20psi mark. Though above this he did see some distortion of the metal electrode ! lol.
