I'm having the local muff shop install my lt headers right now and they say theyre having a problem with the clearance on the plug wire. Or the wires sit on header. I dunno I'm not there right now. Can any1 tell me the issue or how to fix it????

 

Some guys run MSD wires because they have a flexable boot and some guys use wire socks. What headers are you running?

 

Pacesetter long tube armor coated.

 

O5 silverado 5.3

 

only two of my stock wires are against my tubes but ive got boots on all of them. havent had a problem yet in nearly a year.

 

It could be that the wires are too long. It could be the wires just need to be angled differently, coming off the coil.

I use the MSD wires for the Camaro/Corvette as they are shorter than the MSD truck wires. Works great.

 

I had similar problems on an 04 truck, used the MSD wires and it solved my issue.

Here is a link to ours:
MSD LSx 8.5mm Spark Plug Wires

We also have a package deal on MSD wires and NGK Plugs:
Truck MSD Plug Wires and NGK Spark Plugs

 

I run sleeves over my stock wires, I have a couple that rest on headers and they have been fine

 

We used sleeves on stock wires in another forum members truck, and to the best of my knowledge he hasn't had any problems.

 

Do you have round or square coils?

You can run LS1 MSD wires with the round coil packs if you don't want much slack in the wires.

It also depends on if the problem is the boot or the wire itself making contact.
