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 Omar Card

They came in a box with no spacers separating them and the box was torn so badly I can't believe they were all in the box. Also, they haven't had any physical damage and appear to be of good quality. After installing them, as well as all new spark plugs, I had one that didn't work properly. No matter what cylinder it's running on, it's prone to misfiring on idol or at low rpm under load. As soon as the RPM exceeds 2-2300, it clearly starts to shoot properly. I just didn't want to return this reel and decided to try all the options to see if it was something different. It's not like this. Overall I think this is a good replacement for the price and mine may have been damaged in transit although not obvious to the naked eye. I would buy it again but recommend if you have this problem just ask for a replacement and don't do like me. Sometimes our overexperience is our downfall when we should know better. This was on a 2004 Trailblazer 4.2L. I recently replaced two coils so all new coils, spark plugs, camshaft position magnet and camshaft position sensor. All parts serviced as scheduled, mileage just over 150,000 km.
