For Jeep CJ7
Got these to fit my new HEI distributor. They’re longer than I needed, but some mounting brackets and some wire-ties and they work great! Be sure to remember they’re 10mm when ordering brackets.

Good source of power
They are a little long so you will have to figure out a way to tie them don't to give them a good look.

Used to custom build Jeep 4.0 wires
Using this set to custom build a wire set for my Jeep 4.0 with a Viper coil upgrade. The spiral wound wire is quite nice and the copper tap used to bridge the high tension wire to plug and cap clip is quite effective. Nice set and would buy again! Jeep runs great!

Horrible product.
I ordered this set of spark plug wires due to the good reviews. Unfortunately I did not have the same experience as most. At first glance they looked perfect, nice and thick “durable” exterior. On the description they are said to be heat resistant but I went ahead and bought the heat resistant boots just to make sure. I installed the wires and everything worked great, due to the extra length I was able to run them in a way they didn’t even end up touching the headers. After a couples days of driving (my daily driver) I started to hear a ticking noise and my truck would shake, I decided to check and inspect the wires one by one. The first thing I noticed was the discoloration on the heat sleeves but the surface didn’t seem to burn, checked under the sleeves and two of the wires had burned and cracked, current was bridging from the wire to the header. I tried reaching the manufacturer but I have not heard from them through Amazon and I was not able to reach them directly. Maybe I got a bad batch or they are just not what they are described to be. I would NOT recommend this product. I am not too upset just because as a car guy I know that if we want quality we most pay for it and in this case I chose not to. So, Fellas! Let me save you the trouble and advise you, just spend the extra bucks and get quality product for you ride.
