Good vendor!I purchased a set of MSD's 8.5's from Chris/CCP a couple weeks back. He's the lowest price around and fast/free shipping. His wires/plugs combo pricing is a good deal as well.
And for the record I run TR6's.

75k miles on her with a supercharger making 550rwhp and I'm running the plugs that came with the car and some TR6's
I have had some MSD wires to put on for probably a year, just haven't gotten around to it and the stock plugs are doing fine, lol.
There is NO reason to change on a nearly stock car like you have. Just throwing money away.

Unfortunately, I'm in the low mileage, LS3 plug wire(s) falling off club. Not a chance I'm putting another OEM set on. Ordered a MSD set given the lack of fitment information on the GMPP set. Did find the listing for the GMPP truck set which is longer, but I couldn't determine how much longer. The MSD set is 4" longer, so I opted for the standard LS1 set.
General question for folks who have installed the MSDs on their LS3 - still using the factory plug shields? I've read several threads where there don't appear to be any long term issues not running them given the MSD's ability to tweak the spark plug boot/angle.

Just an update. Installed the LS1 MSD spark plug wires. To answer the questions I had a hard time finding answers to:
- Yes, the LS1 plug wires fit with just a slight tweaking of the spark plug boot - the MSDs are bendable so no issues tweaking them. Recommend installing the spark plug side boot first, and then tweaking to provide the necessary length/slack to the coil side.;
- No, you don't reuse the OEM heat shields. Appears to be plenty of clearance between the spark plug boots and the exhaust manifolds;
- Yes, noticeably smoother idle; performance about the same.
I used spray silicone on the coil side to aid installation, and dielectric grease on the plug side to ensure I can get them off later.

I just installed the MSD red wires with NGK TR55 on my 07. I just installed the LG headers and full exhaust w/K&N cai and a 160 deg thermostat, and had the crank pulley installed as well(powerbond). Had the car tuned 2 weeks ago . the plugs were gapped @ 55 , is that too much gap for this set-up?

This is the 55's numbers:
NGK TR55 Stock # 3951 .055 stock Heat cu
If you are going to high power situations or FI, then I'd recommend a colder plug
For the newer Corvettes, I'd recommend the Iridium plug. If you want NGK, then use:
NGK TR55IX Stock #7164 .059 Stock heat Iridium
My car has need of a colder plug so I went with the LS9 plug:
ZR1 LS9 .040 AC 41-104 = NGK heat range 6 (TR6)
Personally, I think you are fine with the 55s gapped as they are.

SPARK PLUG WIRES,,,,,,,,,,,,,,, If you purchase them from WALMART for $19.95 or XYZ Racing for $500 a set,,,, WILL NOT add any HP to your car.
Purchase spark plug wires for FIT, and Quality Materials.
You should stick with the Spiral Core wires.
Same for plugs. None are going to add HP. The rare metal plugs add longevity and enable the plug to survive for 30K-60K mikes without issue. If you are running high compression, the copper core plugs seen to function a little better but need to be changes a LOT more frequently.
