I have NGK iridiums and I think I paid around $45 for the set. In retrospect I wish I had just bought cheapie NGK TR-55'*. The only benefit for the iridium plugs is the long life.... on a NA 3800'* there really aren't any power gains from the expensive plugs.

The TR 55'* are cheap and can be swapped out very easily if you suspect a fouled plug.... a bit harder to do when one has $45 invested in 'em.

Go with Belden & NGK copper or iridium - from the good people at Napa IMO.

Hey guys, after buying the plugs and wires, I've been hesitant to install them for the following reasons. The car is running fine, but I think that might just be because any degradation in performance could be because over 50,000 miles, I may not have noticed it because it is so gradual. I have a friend who works for Matco Tools who says my GM is built to last 100,000 miles before performing this kind of maintenance. After looking through the threads on this topic, I don't really see a solid number as far as mile when is good time to do this. Is 50,000 too soon? Would I be better off flushing the system with some fuel additive and a fresh tank of 91 octane? Would any gain I get from installing the new plugs/wires be worth it in the long run?

Sorry to bring this back to life, but I'm about to take a 1,500 mile round trip and want to get the best performance right away.

Take the new parts with you (and appropriate tools) in case you have problems. If the trip goes smoothly, change them when you return home.

Save your old wires and a couple plugs for emergencies.

will what do you recommend for wires? I'm going to change my plugs and wiers hopefully this spring and wanted to know. I also have a N/* 3800

It was stated earlier that he recommended the Napa Beldens. I too run these on my car and haven't had any problems either, and from what i've heard from others they are pretty good about honoring the warranty if anything does happen. My next set of wires will probably be AC Delcos though just because they match my color scheme better.

Sorry I just saw that...I didn't see though were you could get the NGK plugs at...Does Autozone or Advance sell them?

And I think I'm going to go with Delco wires, were they sell them out?

Intense has the delco wires, as does Rockauto.com last i checked. The dealership could also get them for you but im sure it would be pricey.
