Review on 🔥 6-Pack Premium Ignition Coils Set Replacement for Chevrolet Trailblazer GMC Envoy 2002-2005 Buick Rainier Isuzu Ascender Oldsmobile Bravada 9-7x by Tommy Rao

I bought these for a Trailblazer 03 as part of a complete setup. After installing them my car wouldn't start at all and I couldn't figure out why. It finally started, but ran horribly. I ended up having the car towed to a shop which I never do and they said 2 of the 6 coils were bad. I went ahead and replaced all 6 again with a better coil and now it's working like new again. I didn't have time to return them and wait for new ones. Totally disappointed with this purchase but I think you get what you pay for. If they all worked it would be great. Four of these worked, so buy at your own risk.
