Review on 🚗 ECCPP Pack of 6 Ignition Coils for Cadillac, Chevy, GMC, Camaro, CTS, SRX, XTS, Equinox, Impala, Terrain V6 3.0L 3.2L 3.6L OE Numbers UF569 C1555 D515C - Enhance Your Vehicle's Performance! by Josh Dyer

Just installed and seems excellent. I had Denso on a run of 130,000 km. And that's 60 for 6. Half price. Perfect. As a mechanic I would say they might not last as long but I think they are good for 100,000 miles. Parts machined this way can't do many different things with these coils in their manufacture. There is no reason these reels are worse or better than the Acdelco Denso, just a great price. If I were you I would buy these coils. To update. 9 months later I'm getting bad misfire codes p0300 and p0305. Turns out they were bad. Update: All of these role packs failed 1 to 1. They lasted 9 to 10 months. Average mileage 15,000 miles
