The Tr55's are a good plug, I like MSD wires myself, but those will work too. The gap should be 60.

Also take a look at the AC Delco Iridium plugs and GM performance wires. It has been a great combo for me. Do not regap the Iridiums!

TR55's are a good plug choice. Good to hear about the GM performance wires - I may give them a try.

Cant beat the price performance and durability of the GM performance wires. Get them from one of the forum vendos. They will give you the best price.

Unless you just want to, or you have a persistent misfire, you probably don't need to change out the plugs/wires.

I swapped out my original set at 100K miles, and everything was fine then. I put in a set of copper NGK TR-55s, and ran them until just recently when I pulled them in the process of changing out a set of valve springs (148K miles). If I hadn't already bought a new set of TR-55s, I would have had no problem regapping them (the gap had grown around 6-7 thousandths over the 48K miles) and popping them back in. I did put a new set of OE wires while I was at it, due to damage to one of the wires.

HTH, and have a good one,
Mike

I went with NGK TR55 copper-core plugs gapped at .060" and GM Performance 8mm wires. The copper-core plugs aren't supposed to last as long as the iridium but supposedly deliver a better spark. The wires fit perfectly and accepted the stock metal heat shields. Overall very happy with the setup and koolsox provided added protection against the heat from my headers...

ngk makes the tr55. denso ptj16r15 ran awesome in my car
i have changed to autolight wires seems the same wire as stock
i think any new plug would be fine. youll find that everyone will claim there plug is the best, one ill never run in anything again are split fire they seem to make everything ive tryed them in feel sluggish
