Hello all,

I've done a search but results were less than helpful. I plan on a wire and plug change soon and wonder; what plug is most favored by everyone? I have no interest in the fancy plugs that I feel do no useful good, except put profit into the manufacturer's pocket. I'm looking for a good solid performing plug that will give good results and decent life.

Thanks.
Scott

I prefer the NGK Iridium. They are about $8-10 a plug and will last a long time, plus they are supposed to give a more consistant spark.

You would need TR5IX if you are stock or mild bolt ons.

....and what scares you about using OEM plugs ?

NGK v-power are the way to go IMO. They are a standard copper plug, but super dependable and low on the misfires. Only $1.99 a plug in most cases. Gaping them to .050 has given me great results. They wont last as long as iridiums, but I like to change plugs every 30-40k miles anyway.

Actually, nothing. However, I wanted to get the opinion of others before I made a choice. I've had my Vette almost a year now but, the LS engine family is still new to me. I'm old school and there I knew what to use. From what I've seen this engine has needs and wants and I want to make sure I make the right choice. Factory would be fine and may be my final choice. I was just looking for the feelings of others. In your own way, you voted for the factory plug. Thanks.

I bet you mean 30 or 40 thousand, am I right?

Based on your sig. I don't see any mods. Stock car, stock plug. Yes, stock plugs are more expensive up front, but they last forever.....

I've had good luck with NGK TR55. Nothing fancy but they work.

NukeC5

Yes

TR55 is what I have too. They are the V-power plugs. Very good quality.

YES--factory AC is as good as any on the market--NO HP gain in any plug--

I just put on NGK TR55 V-Power myself, I use them on all my cars and never had a problem. For wires I use Taylors.

If you don't mind gapping, NGK TR5.

NukeC5 can probably send you some with only 40 miles on them.

Just a word on factory plugs - the ones in my 2000 were JUNK.
Those "double platinum" plugs used a little platinum "puck" welded to the ground electrode, that was notorious for falling off. The two results were that it could possibly catch on a valve seat as it exited the engine, and that it instantly increased the electrode gap about 0.015.
When I removed mine at 15K miles, I found two "pucks" already missing! At some point Delco scrapped that design, as my '08 Caddy platinum plugs don't have the "pucks". If you use those newer versions in the recommended heat range and gap I guess the Delco would be OK.

I made the edit

Curious, How many miles you guys seeing on the NGK TR55s?

RonSSNova

It was a joke......get it?

DARRYLZO6

Absolutely. also using a better wire eliminates radio frequency interference. A good thing.

NukeC5

Oh yes, that's how I took it! No worries the smash face was just over my forgetting to put k behind the numbers.

RonSSNova

Good!

I'm sneaking off in an hour to go try out my new drag pack, the air is good, cool temps!

BTW, I run TR6 plugs now, they afford a couple more degrees of timing w/o KR.
