Another vote here for AC Delco.

ACDELCO 2nd choice would be ngk. But every gm ive owned has had delco iridium plugs.

To add to this; I've been told several times that these engines can be temperamental when non-OEM parts are used.

A little birdie once told me that some Delco plugs are rebranded NGK's.

just got my delco's from rock auto. and for about half price of what the local parts places wanted.

They're the best. No sales tax for me in CA and they always have a 5 percent coupon floating around on the interwebs.
