spark plugs for boosted apps?

[knuteiriktveiten]

hello, I was wondering if anyone knew the best sparkplugs to use with a boosted gsr?

I know that some plugs take up more room in the combustion chamber giving you slighty higher compression. The ones i know that do this are Bosch Platnum +4's and the NGK's.

I am using NGK's in my N/A b16 and on the dyno they acually gave me 1 more whp because of the compression increase! So I would stay away from these with a turbo.

I only run NGK, for me they work I'm sure there are other choices but they are cheap and they work well. If you are not running a hot coil gap at 28 thousands.
