Yeah I'm running 1 step colder NGK copper plugs. You should always run 1 step colder when going FI, so the plugs can pull heat out of the combustion chamber.

Beerviper is correct...don't go w/ Platinum either...no good for FI. Iridium or Copper is the way to go.

Finally picked six up from NAPA. Autozone and O'Reilly's didn't have em in stock.

What should I gap them to?

They should be pre-gapped ... I checked all 6 of mine and they were right around .042. Spec is .044 which should be fine. As long as you're not running high boost (like above 12psi) then that gap should be fine, otherwise I've heard of the boost blowing the spark out!

The larger the gap the better as to create a bigger spark and good ignition.
