MSD32813 Black 8.5mm Super Conductor Spark Plug Wire Set

Would be 5 stars but one of the terminations pulled off in normal use w/ dialectric grease on the boots. Weird thing about the purchase though, I bought the first set, one broke, instead of being able to do the amazon swap out, I had to buy another and file a return claim on the first set. Not sure if it's the seller policy, amazon made a change, or what.Update: I bought a second set and they're all falling apart too. I expect better products from MSD. Seems like cheap Chinese garbage. Save your money and buy the cheap ones. Complete disgusted and disappointed. Accel or Mallory, here comes my money.

Have had these on my 2015 Camaro SS/RS LS3 for about a month now. Must say what a difference. Cleaner and more rapid throttle. Surprisingly I went from 17.6 to 18.1 in gas mileage. I have an aggressive driving style. In other words I drive the car like you should drive a V8 6 spd manual, Bought MSD because of my many years of using there product and the quality I have found. These wires are much beefier than stock and do not need heat wrap or shields around boots. Needless to say I will be buying their coils next.

Lengths were perfect and car is running quite nicely. MSD has always made a great set of wires and I'm happy to see that they continue to do so. Installed onto an LS1 in a 2001 Camaro Z28 and should work for all LS1s with the coils mounted onto the valve covers.

Business

the last set lasted 2 years at 4500 RPMs, if one of them hadn't been touching the header, I wouldn't need a new set
