I bought the ones with the high heat boots. I have pacesetter long tube headers on my LS1. The high heat boots are long and thick. A couple boots almost touched the headers. They barely clear the metal but they fit. The length of the wires is perfect. Some people complained of them being too short but for an LS1 they are fine. I would recommend these plug wires.

At first the wires appear too short but it's actually because the rubber part is longer. It's hard to make them work with the stock heat shields. Overall, they seem like a good product.

These are NOT MSD manufactured/assembled spark plug wires will not fit at the Coil End. The crimping on the coil side is not properly crimped causing the insulation of the wire to misaligned…see attached pictures (the red/white insulation is blocking the coil plug to be inserted properly. These plug wire arrived in a plastic bag not on a MSD box. I have to order original MSD in a box which it a little easier to install on both end.

Received order very quickly. Fit and finish is outstanding. Very satisfied! High temp boots where a great choice, much sturdier than regular ones.

My car is running smoother, has more power and is getting better gas mileage. This is my second set of MSD plug wires and they ALWAYS perform up to expectations. -James
