MSD Spark plug wires --any comments?
Just replaced my opti with a vented dyna spark, and new plugs, and GM wires. Wires already shot maybe I got a bad batch whatever.
Want to put MSD wires in with the new wire looms, has anyone had any experience with the MSD wires?

I think you'd be better off with the 7 or 8 mm Taylor wires for aftermarket, although I had good luck the Belden Super Blue Premium 7 mm Ignition Wires sold at NAPA.
The O.E.M. Delco/Packard wires are plenty good, too.
MSD's quality control seems to be slipping judging from recent unsatisfactory comments here.

I've been running the MSD wires for over 5 years. They work great. Now for the rest of the story..........These wires are too big for the "cloverleaf" loom under the a/c and alternator on a LT1. I fabricated my own looms using GM's idea, but smoothing out the wire's flow. Also, I have headers and the straight plug boots just don't work as they get too close to the headers. I called MSD about it and they sent me the required 90 degree boots with a cutter and crimping tool. This allowed me to really customize the wire layout. Nice company to do business with.

iv always had great results with msd products, but not with their wire set for the lt1. i had huge problems getting them to "snap" in to the plugs and distributer, and when you tried to remove them they would just fall apart (yes i used the plug boot grease). switched over to 8mm taylors and they seem like high quality pieces.

I'm running them also. I can't complain, they've held up well. I use boot insulators so that helps with the heat.

Now that I've put NAPA premium wires on, I'm still getting an ark when I look at the wires at night. I've also changed my plugs which were new to NGK platnium spark plugs. It runs better, but it's still having some issues and arking. getting frustrated...new parts should fix the problem. Does anyone know what else could cause the arking.

New wires can be defective, too, out of the box. Also, did you remove all the O.E.M. sections of black corrugated flex tubing that came on the old wires? It's there to minimize the effects of wire chafing and should be re-installed over the new wires.
Take a look at your coil and see if the arcing is occuring near it, too.

As for MSD, that is what I just replaced. I had them on for about three years, and less than 15K miles. They were toast!

I have the same problem with my new Delco plug wires. I am using the AC Delco LT4 wires (Amazon, yeah- strange place to find them). I just put them on checked them in the dark, and I am getting arcing at the plugs, and at a couple of the wire looms.

You didn't damage the larger diameter wires with the OEM dia. looms did you? just a thought, especialy if it's doing that in the same place with more than one new wire. The arcing at the plug can be nornal (as stated in your other post) as long as it's from the plug and not arcing through the side of the boot.
I did get the note on the corona effect, and I think that is what I am getting. It is not going through the side of the boot. I will check again tonight though.
-Thanks!

The MSD wires I bought, at Summit Racing equip, were crap right out of the box.
The coil wire spark arc'd against the water pump housing from the boot-to-wire junction.
I had to electrical tape around the boot-to-wire junction to get the spark arc to stop.
Its not cool having an ignition source under your hood. (for a fuel injector leak, methanol injection leak (if you run that like I do).
They are expensive and junk.
Go with taylor.

Curious if anybody is running Magnecors? I've read everything they explain on their website and am wondering if anybody is happy running their sparkplugs. I need to replace my cruddy stock plugs soon and I've heard nothing good about MSD lately.
