Spark Plug Wires
Needing to do a tune-up on my 04 LS1 and was wondering which way to go with plugs and wires. The engine is all stock. Was wanting to go with MSD red wires for a little dress up, but not sure.... Thoughts?

How would you like a set of wires that have STAINLESS STEEL cores, RF Choke and marine style plug boots?
I have been using a set on my 8.1L Chevy in my RV, which I just sold, for over 4 years and have had 0 issues. No misfires or burnt wires. I will be testing a set on my, new to me, LS3 along with a new set of 41-110 plugs. The only requirement is you must use the stock heat shields.
You need to check your heat shields... the inside should be kinda on the orange side of brown. If they are dark brown they are toast. replace them. You can get them from Rockauto (part # 8006) for $2.87 a piece.

I use ngk tr55 plugs, and msd wires with the bendable/adjustable plug ends. the wires I bought are for a truck.
the are a little bit longer,(1") vs the corvette wire set. IMO the msd corvette wires were too short, and the coil ends would work themselves loose
msd may have corrected this by now, it's been two years

You may want to check your plugs wires at night... You may be surprise that they are providing a light show under the hood.
Are you using the IRIDIUM version of the TR55 plugs? That is what the 41-110's are. FYI - if you look real close you might find that the plugs are NGK assemble in the USA!
I found this on the 41-101 plugs I used in my 8.1L Chevy in th RV.

I just put some ACDelco 41-110 plugs into my Mom's LS2 TBSS. The original plugs (same plugs) still worked and looked good at 100k miles so they seem like a excellent option. Many people also run the NGK TR5's and TR55's. The TR5's and TR55's are the same plug with different gaps. I have TR5's in my Z and they seem to work well.
I've always had good luck with the stock plug wires on many LS vehicles so I see no reason to run anything different.

whichever route you go make sure to ohm them out before installing to make sure they are within spec... I have seen msd wires way out of spec right out of the box... msd uses nice materials but I believe the cause for high resistance in some of their wires is the way they are crimped... I used msd bulk wire along with their ends and made my own when I relocated the coils

Just finished the plugs and wires. Either the factory or one of the previous owners put Copper Anti-seize on the plugs and boot grease as they came off with not to much effort.
I did NOT lose any wires and the plugs looked good (nice chocolate brown). The gaps were a bit off. .034 to .038. The plugs were 41-985's which are the Platinum version. The 41-110's are the same plug in Iridium and the gap is set at .040 per spec.
Bottom line... MY butt dyno says it idles a bit smoother. Checked a few things with my scan gauge like LT/STFT, MAF, IGN, KR etc... and they all looked good.
