Here's a photo of my stock #4 wire after about 1500 miles AND having the DEI heat shield in place....the wire has been wiped off, the white stuff visible will not wipe off. I wouldn't be surprised if I have to replace my MSD wires every few years.....

what made you think of that? i thought you've had the msd's on for awhile?

 

I have, since 1500 miles. Yesterday I put some dielectric grease on the MSD termainals since I didn't have any when I put them on originally. I've saved the stock wires which join my stock exhaust and stock PCM in my garage. The MSDs don't show any discoloration as of yet, and the worst of the summer is over, so maybe they'll last awhile and I can save the $20 I was going to spend on the "heat shield" from Modern Performance.

 

i've been hearing about the 4th wire for a while now, i checked my 03 srt for any wire damage but found none. i live in dallas, tx, so it gets kind of hot down here. ill try to take some picture so you guys can tell me wich wire are ya'll talking about... or if you guys have pictures it will be alot better...

 

It's the last spark plug wire going into the hole on the right side (as you face the engine). Follow it (it's pretty short) and you'll see how close it gets to the turbo.
