NGK Plugs
I ordered a set of NGK-TR61X today!!
A variety of people recommend these plugs for modified engines or forced induction applications. They're an improvement over the OEM spark plugs as the OEM spark plugs tend to knock much more. (If you log data with a DiabloSport Predator, DiabloSport Trinity, or other such device, you'll be able to see the knock retard climb as the RPMs increase.) I immediately noticed the increased performance and I'm very pleased to put the increased power to good use.
This info From the LS4 Store Wes can help you with any info for the LS4
