Review on 🔥 High-Quality MAS 6 Ignition Coils UF303: GMC Saab Buick Isuzu Chevy Trailblazer Colorado Rainier Canyon Envoy Hummer H3 Olds 2.8L 3.5L 4.2L C1395 UF-303 Replacement by John Miranda

Installed on my 06 H3 to solve a misfire problem. No problems so far, assembly looks good. The descriptions give me some confidence in the build quality. The best OEM alternative in my humble opinion. But let's see how long it lasts. Ignition update for my H3. My car's idle speed seems a bit low. Power outage, almost stalled in the parking lot. I will then go back to my old OEM coil and have no more idle problems. I thought replacing the new coil would fix the misfires, but then a new problem started. Returned! No bueno!
