Now I'm not too familiar with the plugs either, but does NGK make anything equal to the AC DELCO that is cheaper price wise and just as good as OEM or just stick to the AC DELCO's? I'm going to be picking up a spare set to have on hand for down the road when I do need to replace mine (I only have 38k miles on my car and if it stops raining this week, I'll check mine out and make sure they are looking good and gapped properly).

I should mention I frequent a shop in Pensacola called RPM. We had an LSJ with e3's come in where the end broke off the spark plug, dropped int he motor, and destroyed it. The company, e3, purchased a new engine. I had them in my Lotus, got some misfire, took them out and the whole damn plug would rotate inside its shell, that and the ends were mere MILES from breaking off.
There my 2 cents.
There my 2 cents.

I wouldn't bother if you're stock. The AC Delco's are designed to last until around 100,000 miles. If you feel compelled to change them, stick with AC Delco's unless you decide to add some performance enhancements that require colder plugs. They may be a bit more expensive, but generally you won't have teething issues with them.
I was just wondering if the NGK's are any cheaper and if they have a factory equivalent for when I do replace mine. If I go with ZZP's SC kit down the road, then I would get NGK's for sure.
So my main question was whether NGK makes something comparable to AC Delco's that are possibly cheaper.
BTW, anybody know the part number on the AC Delco's so I can have my sister-in-law check pricing on them. I'm talking about the stock AC Delco's for the 2.2.
