Need to do a plug and wire change for an LSA (first time) Hi All...
I just bought a 2013 ZL1 this week with 60K on the clock. From what I can tell there are long tube headers, a 2.5 inch top pulley, and a CAI. I have no idea of the size of the crank pulley.
I'd like to to a plug change and need to know what the torque specs are on the plug and from what I read the TR6 plug is the way to go. Normally I would lube the boot and plug with electrolytic grease the put anti seize on the threads then torque to spec. Is this still ok?
What should I use for a gap?
I have an inch pound torque wrench, swivels, extensions, and spark plug sockets. Do I need anything else?

Personally, I’d go back with whatever plug is in it and I would mimick the same gap. Heck, with 60k miles, I bet plugs still look great. Pull one and see if it’s a waste of time to touch them before you go get a new set..

I hear you, its just a ritual I go through whenever I buy a used car. I hate not know what when and where things like plugs and filters were replaced. I noticed a tear in one of the plug boots and it has a slight stumble from time to time. I figured that's a good excuse to do a tune up.
It looks like the gap is 0.04 or 1 mm. Not sure what the torque spec is yet.

Here's what the chilton manual says on torque specs
Tighten the spark plugs. Tighten the engine spark plug on a NEW cylinder head to 20 N·m (15 lb ft) and the engine spark plug on subsequent installations to 15 N·m (11 lb ft)

AC Delco 41-104 spark plugs are factory fill for C6 Z06 and C6 ZR1 engines. I've been using them for years to over 660 rwhp. N/A and supercharged. They come ready to install. Nothing wrong with the stock plug wires either. If you feel the burning need to install something different, by all means, do it. I do put a little dab of never sneeze on the threads too. Wrist tight. I've had TR6's bad from the factory. Never a problem with the 41-104's.
If you change plugs often, maybe the TR6's fit your program. If you're the screw them in and worry about something else type, the AC Delco's are a better deal.

Nice to know things evolved and anti-seize isn't absolutely necessary with NKG's.
FWIW - always used very thin film of anti-seize on the ~8 plug plugs my 99 T/A had with no issues. Normally GM LS aluminum heads have a plug torque of 15 foot pounds new and 11 foot pounds there afterwards. l always used a torque wrench not having those mad mechanical skills & feels to play it safe.

I remember a car came into our shop when I was 18/19 that her B/F changed the plugs. It was running on three while the forth plug was hanging from the plug wire. He stripped it out. Lol.

thanks. I never heard that before. Is it a common practice from all of the plug manufacturers nowadays?

Going to wind up having a shop do them. Took it to a tuner today and when he took it for a drive the injector duty cycles went up to 126% so they're going to change the fuel pump. While its there I'll have them tune it and change the plugs. At least it'll be safe now and feel much better
