A Good Coil At Last
I have a 2008 Mustang GT with a lot of upgrades like cams, headers, etc. When the cams went in I went with the Granatelli Motorsports Pro Coils based on the reviews I read. Well, they were a problem from the get go. The electrical connections were not in the same position as stock and stressed the wires, one of the coils was broken by the cam installer as he snapped the electrical connection. Anyway, the car was running really rough, but I attributed it wrongly at the time to the cams being so radical. I then put the stock coils in but battled with a check engine light coming one about every two weeks. To make a long and painful story short, I pulled a set of Champion Platinum Plugs out and went with the Ford Racing Plugs one step colder, and with the MSD Coils. The MSD Coils are so much better than the GM Coils as the location of the electrical connection is close to stock, and the coil connections are better with the flexible similar to stock spring. The car now runs better and has ceased throwing the Check Engine Light with different codes all the time.
American Muscle was great as they helped me to track down my problem and were more than prompt in getting me the coils the next day when I ordered them. American Muscle is a great company to deal with from both a sales and service aspect. Plus the MSD Coils are great and look good, as well as putting out the extra spark I needed for my increased HP. I did not pick up any MPG but that is probably due to my putting in larger injectors.
Bottom line, if you are looking to upgrade your stock ignition go with the MSD and don't be afraid to talk to the sales and tech personnel at American Muscle as they are great people to deal with.
