Tune Up

[Robin Derrick]

So I'm going to be doing a tune up on my 02 this weekend. I've got the AC Delco Platinum plugs, what spark plug wires do y'all suggest?

I bought the Magnacore Wires and love them. It was a noticable change in the way the truck performed from the old (150k miles) wires. Most people suggest the ACDelco, as these trucks seem to be finnicky about certain things.

I also used ACDelco Iridium plugs.

i used the delco replacements. Everything went fine, with the exception of i had a tough time getting the new plug to thread into the drivers side front cylinder, i forget which # that is. Thought i had stripped it, but after some patience got it back no issues.

Which mm did you go with? I was looking at the 8.5, but not really sure if I need that or not. The truck has an intake and exhaust on it.

41-110

they aren't listed as an application for our truck because they still only list the platinum. But this is the direct replacement for the platinum -> Iridium.

**EDIT**
I bought mine at AutoZone with the assistance of a helpful employee there.

Also, be ready. the plugs for cylinder #8 and #4 are a PITA.

on #4 (the closest to the firewall on passenger side, you can remove the mount bolt for the oil dipstick and wiggle it out of your way, but its almost easier to get to from the wheel well. #8 (closest to firewall on driver's side) is just a difficult damn job.

For #8 & 4 I use a 3/4" extension and that's all you need. No swivel etc. SK makes one I think they call it 1/2" but it's more like 3/4.

I removed the inner fenderwell cover to get access to the hard to reach ones.

Believe me, this tiny extension on the plug socket is the way to go. No need to remove anything, nothing else needed. It makes it so easy you'll be amazed.

I had the same problem. Got the plug in and am hoping it's not cross threaded. No leaks or issues for 10,000 miles.

This, makes the job easy, well easier....

I went with these. These are 10.4 mm. My headers we're burning the stock boots.

 

[Danny3737]

It helps to put a little dielectric grease inside the boot to help slide it over the plug

Ac delco has $3 off each iridium spark plug
$2 off platinum rebate going on right now

Hi All
I put a little anti seize lubricant on the threads.
I changed the first set at about 100k and getting ready
to do it again as I have 207K miles now. I changed the wires
the first time.

 

[Danny3737]

I really don't like putting anti seize on the threads because there is a good chance of over torqueing and stripping the threads. Its a big no-no when installing plugs on aluminum heads. I just thread them down until snug, then give and extra half turn.
