What part numbers are the MSD wires? I was not able to find any online shops, even summit that said they sold MSD custom fit wires for the 2000+ 5.3L.

I am also interested in the Taylor Thundervolts. Anyone know where I could get these too?

 

i bought some thundervolts from truckperformance.com. i got em in the mail today and woah...these things are huge. they made a considerable diference too, made the truck a little more alive. kinda pricey though.

 

I lost the part number but they come in tomorrow, so I will update you guys when I get them.

 

The MSDs came in today. Part #32829. I installed them along with a new set of NGK TR55 plugs. I was a bit disappointed with the wires. They are about 2 inches longer than the stock wires, and 3 of them touch other stuff in the engine bay. The back pass side one, and the front and 3rd driver side ones all touch stuff, and I'm worried about them wearing through the insulation. But I was surprised at the seat of the pants gain. But it does make sense. If you do intake/exhaust/tuning mods, you probably need fatter wires to make a better spark. They were worth the $55 dollars, but it would be nice if they were an inch or so shorter. Don't they test fit these before they manufacture them?
