Review on 🔥 8-Pack Ignition Coil Set - Replacing 12558693, GN10298, C1208, D581 - Compatible with Cadillac, Chevy & GMC Vehicles - Escalade, Silverado, Avalanche, Express 3500, Suburban, Tahoe, Sierra, Savana, Yukon by Evan Larson

I have a 2004 Chevy 2500 HD 6.0 with Vin 8 "U" installed. I was hoping to resolve a generic P0300 code, which indicates a misfire on one or more cylinders. The truck has done 106540 miles, I also changed cables and spark plugs. Some of the coils were chipped and rusty, the price can't be wrong. A direct repair requiring 10mm took about 15 minutes to replace all 8. They were on the truck for about 1 week. The truck runs and starts better with the changes but still has the infamous p0300 code.
