    Manufacturer's Part Number:
    Rated 5 out of 5 by from Seat of the pants I purchased these coils to replace 11 year old factory coils on my 2004 Mystichrome Cobra convertible. After reading all the articles on the web about being a waste of money I was very skeptical of any improvements over stock. Not sure how other replaced these but after reading a lot, I purchased new NGK Iridium plugs, Gapped them to .045 and installed the New GMS coils. Wow, What a difference. It was like adding 50HP to that car. THe forced induction really loved the added spark. I cannot believe the difference for 300.00 total and about 2 hours of my time. Other must of did something wrong. These really do a great job and improved throttle response on the 32 valve 4.6 engine. I really do not post many reviews but I just wanted to set the record straight, Get these and you will love them on a Supercharged Cobra !!!!!!
