best plugs in Gen4?

Yep! Advantage of getting them through ZFG, is they are gapped to exactly what they need to be. Little piece of mind. The gap is just as important as the plug itself.

I just got them installed gapped from ZFG @. 028. They're awesome.

The plug recommended by Loki is one step colder. I installed them and I am tuned... use .028 gap and runs like champ.

They would be wrong. That was explained earlier in this thread. 0.031 if staying stock, 0.028 is what most tuners are recommending for normal tuning.
