I installed these based on the company reputation. My Mustang ran great at first. Then it developed a miss at idle and when first accelerating. I have a buddy who is a Ford tech, and he told me to substitute one of my original coils, one at a time, and see if that clears the problem up. Sure enough, it did. I swapped the defective Edelbrock coil back in, and the problem came back. So the coil is defective. As much as I wanted to like these, I would not recommend them to anyone.
