Review on Enhanced MSD 8227 Blaster TFI Ignition Coil: Maximize Performance with Reliable Ignition by Alex Maynard

AVOID! Avoid. Do not buy. I installed this coil in my Bronco which I drive about 5,000 miles a year. He worked for about 9 months, after which he left me on the side of the road. I had to haul it home 20 miles then put a 5 year old coil in it and it works fine. I seem totally confused. If you read all the reviews in full you will see that many other people had the same problem after a few thousand kilometers. If you buy this keep a spare coil in your glove box.
