I'm in the process of replacing both my spark plugs and wire set in my 2012 LS3 vette. the NGK TR61X is it a good spark plug replacement? or just stick with the OEM ACDelco replacement? when replacing the wires must i get a wire set that has a heat shield? ACDelco has replacement wire sets with both heat shield and NO heat shield, does it make a difference? Are all the spark plug wire replacement sets about the same? also does anybody still use anti seize when installing spark plugs?
THANKS BOONIE.

The stock stuff is pretty hard to beat. If your engine is stock, replace with the stock parts if you think anything a awry. I use just a dab of anti seize on the bottom of the threads when replacing plugs. Doesn't take much. You can over do it.

I went with ac delco 41-104 (same plugs for the c6z06 and zr1) and set of msd wires (good reviews)

I did mine last year and went with ACDelco 41-110 and Taylor Cable 84044 wires. Very happy with no issues.

1: The OEM plugs and wires are good for 100k miles. If you're sitting at 50k you're wasting money.

2: Just get the OEM 41-110's and OEM wires if you are stock or very close to stock. Again, wasting money otherwise.

Stay with oem plugs and wires for a stock corvette.

No anti seize on new AC Delco of NGK plug threads needed, the threads come with an anti seize coating on them.

Do not use a colder plug (TRIX 6) unless you are running 75 more horsepower or higher compression. Reuse the heat shields, just slide the heat shields off the old wires and slide back on the new wires.

If you change the wires, add a little dab of dielectric grease on the inside tips of the wire boots themselves. It will help prevent moisture and make for an easier install and future removal.

how did that setup work for you?

I only have headers and intake and I needed to run colder plugs so YMMV on that.
