first off all, I 100% sure that ac delco will not let ngk made plug for em. This dude over other site, out off no where say " Ac delco plug made by NGK " , that got me tick, NGK is good plug. What you guy think ? here the pix he post that how he say they both are the same, BS DENSO iridium look the same too.

My old plugs looked very similar to the NGKs too. The old plugs even said "Japan" and "Denso" on them. I'm the only owner of my car. My NGK plugs only said "NGK" on them. I would say that AC Delco does NOT make NGK plugs.

Why are you sure they would not make them? Many AC-delco parts are reboxed, the last AC delco wheel bearings I bought were reboxed (nsk I think?) and were available for 1/2 the price at napa.

I know, I was agreeing with you.

I am in the parts business, and NGK definately makes some spark plugs for AC Delco.

As a matter of fact, most anything that's AC Delco brand is made by the same manufacturers that make the majority of aftermarket replacement parts. Eg. - Gates makes their belts, and Raybestos makes their brakes.

If you think you are buying an O.E. part because it's in an AC Delco box, you're way off.
