I have bought 3 sets of these over the years. I typically change plug wires when doing the basic tune up along with cap, rotor, and spark plugs. These seem to hold up well and do not corrode internally causing poor performance between tune ups or even when I have extended time between tune ups. I have over 460K on this truck and it is due to regular maintenance as well as using good quality parts.

I searched for a good quality wire set for awhile. I chose these & I'm very happy with them. They look like quality wires & come with dielectric grease. Also made in the USA. Great product!

Received the product on time, worked right out the box. I used these wires with AC Delco for my 1996 Chevy Tahoe 5.7L, and increased the performance, response time, and gas mileage. I do recommend these wires combine with AC Delco, had no issue with it fitting with the wires. I love the product and will continue to buy.
