AIP Electronics Dragon Fire High Performance 10mm Spark Plug Wires Compatible with 1999-2019 GM Chevy GMC LS1 LS2 LS3 LS6 LS7 Vortec 4.8L 5.3L 6.0L LS1 100 ohm/ft, OE Heat Shield OEM Fit PWJ256

I'm happy with the purchase but I should mention that this set does not fit the coils for my 04 Silverado z71 5.3L. The length is fine but the coil side connectors are too big for my factory coils. I'm pretty sure Amazon did not verify these to fit my truck so I don't hold them responsible. Other than that, they seem to work great and the build quality is good. Thick wire/insulation should make them more than durable for my farm truck operations.

Very high quality, my husband really likes them. His GMC is running so much better. Thank you!

I had a slight roughness at idle on my 2011 Corvette LS3. Installed these and the roughness is gone; and I noticed a big difference in the acceleration, too! lol - as if it wasn't 'already' tire-smokin' awesome!! 100% perfect fit; worth the price; and - they look good!

I received them as advertised haven't installed them yet they came on time actually a day early 👍🏾👍🏾

Other than them being shorter than I had expected they came loose in a usps bubble bag and was looking forward to the cool dragon box as depicted in picture description. Other than that I have previously had these wires installed on my truck for over two years and I think there awesome in my engine bay for looks and performance!
