100 dollar leaking MSD plug wires GRRRRR!!!!

Well just to catch everybody up on my little dillema i've had with my car the past month i'll fill you in.

The car's been doing alittle pinging and a bit of part throttle surging for the past month and it's been pointing me in hundreds of different directions.I checked the egr first,nope. Then I checked for bad fuel,nada. Vacuum leaks? checked. Plugs to hot? checked.Where do I go from here you ask?

Well I decided to do something I haven't done in quite a while.I started the car up in my driveway with all the lights out and I started looking for leaky wires and low and behold 2,4,6,and 8 plug wires were lit up straight under the boots them selves!! The same goes for the other wires too.What would cause this and what can I do the remedy it?

Do they have a warantee of any kind?
I'd think they would.

Plain jane bosch ones have a lifetime warantee, and are $40 a set. You can try those.

What would cause my wires to do that though?It looked like they were either arching to the nuts on the plugs or to the block.Wires 1,3 and 7 looked like they were arching all the way up to the cap.I don't want to spend another 100 dollars on wires.What would be a good 8mm or better alternative?

HONESTLY I GO THROUGH THE JUNKYARDS JUST TO CHILL AND TAKE THE 8.5 MM'S IN DIFF LENGHTS AND I PAY ABOUT .75 CENTS EACH. ACTUALLY SOLD BY AUTOZONE, BUT IF THEY BURN ....SO WHAT I HAVE EXTRAS. AUTOLITE 8.5MM IS WHAT THEY ARE. ALSO YOU MIGHT WANT TO USE DIELECTRIC GREASE ON THE BOOT TO HOLD THE SPARK IN........MY .........................................YES I AM FRUGAL BUT NOT CHEAP.

d00d you got to LAY OFF THE ALL-CAPS. It's super obnoxious to read, and makes it LOOK LIKE YOU ARE SHOUTING AT US. There's no excuse; not "it's too hard to do it right", least of all; the rest of us manage it.

I agree with the Taylors; I've been using their Spiro-Pro ones on all my cars, boats, etc. for well over a decade now.

Since I don't want to make anybody mad, I'll say this is just my
If the wires are not burned (ie: almost new) and they are arcing to the hex of the spark plugS, this is a spark plug problem. Most of the time it is from contamination on the outside of the insulator. (such as paint overspray, antifreeze or salt like chemicals) I will also add that this condition will not be visually apparent. The plugs will look just fine. You can change the wires continuously but leakage over the insulator will continue. Don't pitch a perfectly good set of wires. Change the plugs first.
I encounter this a LOT in my work with units that work around chemicals.
