[Turbo38V6]

What gap are folks using (or suggest) with the E85, a TR6 and Autolite 474 plugs? 160 lb injectors, E85 car pushing 30 psi.

I don't think you can gap those plugs having a cut back electrode.

So that's what I thought too, the cut back electrode didn't lend itself to typical 'gapping'. First time I worked with a plug like that. Thanks for that feedback.
