    Rated 5 out of 5 by from Easy Peasy I bought this MSD coil about a month ago, It took me about 15 minutes to install and it was way easy. It comes with a easy to follow instructions and it was the same fit, it works like a dream!

    Rated 1 out of 5 by from Not worth it Was able to drive my car 20-25 times after installing this coil then car just quit starting. Through the process of elimination determined it was this new coil that was bad on a brand new distributor I had a mechanic install. Put the old coil in and no problems since. Definitely regret purchasing this coil, would advise trying the cheaper aftermarket coils to anyone looking to upgrade.

    Rated 1 out of 5 by from not good bought this to replace my existing HEI coil and when replaced my motor would act like it was missing at low rpms but when I put the old one in I had no issues I guess brand names are not always the best
