E3 sparg plugs?

The guru once said, the factory validates OEM parts, if you buy aftermarket parts YOU do the validation. If you have trouble down the road, you may overlook the plugs because they are new. If they were AC plugs you COULD overlook them, after market plugs will always be suspect.

A few years ago I put a Bosch in an 86 Corvette and promptly took them out because it would hardly idle.

Yep, AC Delco plugs are proven by a world-class engineering staff.

Anything you hear about other plugs is mostly anecdotal information. I'd recommend sticking with the proven winner. You simply can't go wrong.

With other plugs you risk stepping over dollars to pick up pennies.

The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved. - Ludwig von Mises

All of these "funky" dual electrode, tri electrode, quad electrode spark plugs have been PROVEN to accomplish nothing... In independent test after test... No difference. Car Craft magazine did a test about 3 months ago and in the high compression SBC they were testing... Old School single electrode AC Delco plugs made the most power (and cost the least too).
