My ride turned 82K and was wondering if you fellas are changing plugs.


If so what are you buying?

Don't have a Sub. or Tahoe but my 2008 Equinox started missing at just under 70k. Changed wires and plugs(NAPA wires and Delco plugs), cured the problem. So much for the 100k Iridium plugs!

Whats a spark plug? lol.

I did them last around 60,000 on the Tahoe. I did the split fire thing I think. May do them again at 100k, this weekend if I'm bored.

need to do the V6 in the Tribute... the back three are a PITA!

Any word on E3 plugs?

I just ordered plugs for the Tahoe and Mazda.

NGKV-Power Spark Plug
Part No 2238

LIMITED LIFETIME REPLACEMENT 8 Advance Auto Parts

I'll let you know if it runs faster and jumps higher.

These had the best rating for the lowest cost...

I did mine at 102,000 miles. They looked almost brand new when I took them out. Could have gone another 100,000 miles. Replaced them with the factory AC Delco plugs. Can't argue with success.

I replaced the OEM plugs on my '01 right around 100k miles. It was still running fine. Plugs looked pretty good.

Went with NGK iridiums.

At around 185k miles, it started idling roughly, losing power, and was harder to start. Plugs were totally trashed - eroded electrodes. Not impressed at all.

Went back to AC Delco Iridiums.

I change mine every 30,000 miles just to be safe.

Just did mine at 196k. Not sure if they had ever been done before or not, but I believe they had the old part no. on them.
