    All problems listed must be for an older version...

    because all 8 went in fast and didn't have any of the fitment problems suggested here. At least not with this, the second batch. The first set of coils I got from here, one went bad. Also, the fitment on my first set was much more difficult. These slide on perfectly and the feel is great- Everything feels instantly... tighter

    Good Product - Some fitment issues

    Throttle Response is noticeably better after installing. Shop that did the install for me noted that the angle is different from the OEM coils but that after some finagling with moving a sensor around, they were able to get them put in. Good product for the money but just be mindful of some minimal fitment issues versus stock.

    I have some of GMS coils on my '04 GT and they do great, so I figured I'd get some for my '08 Bullitt. I was disappointed to find that they weren't the same molding as the factory which, though manageable, didn't fit as well as factory, or as well as the others for the '04. Instead of the connectors being at the proper angle relative to the mount tab and tilted up to accept the connector they were at least 60 degrees away from stock and angled straight out. The boots were shorter as well, although it looks like the plug connectors were long enough to reach the plugs and they seem to work ok. If it wasn't for the higher performance capabilities, I think I'd have returned them and gone with Accel or MSD due to the factory like construction.

    I bought these about a year ago - was very happy with the performance bump, and easy install. Two buddies also bought them with me. About six months later, I started getting a check engine light, and sure enough, one of the coils went bad. I took it out, GMS was nice about replacing it. Now, almost six months more, same thing. My two buddies that bought them? One had the same thing as me, one failed in a few months. The other friend has had no problems... For me, I'm just not happy with how fast they're failing, and I'm ripping them out today. If you do your homework, you'll see a lot of people saying the same thing about the GMS coils, they just fail entirely too fast. Beware!

    Just popped these bad boys in. I did my research and even went so far as to read the responses that JR himself put up on a few sites. I decided that these GMS coil packs were going to be the best bang for my buck. Coupled with my new Bama tune (free tunes for life!) I am very pleased. I will be keeping my eye on the MPGs though. They might go either way. I can feel the punchier acceleration and slightly quicker tach. Very easy to install. It took me longer to load the tune than to swap the COPs out with two guys.

    Easy installation, diappointing results...

    I was debating back and forth on these or the MSD. I decided to save a few bucks and get these. Installation was easier than I thought. You only need once size socket, extension and ratchet. The only one that is difficult to get to is the rear coil on the driver’s side. I have a Whipple SC so the throttle body was in the way; I recommend moving it to save time. I installed the coils and new plugs at the same time. Afterward the car ran bad; it felt like it was missing under throttle. I replaced the plugs back to stock and still had the same problem. Then one-by-one I replaced the coils and found 1-2 where bad. It was disappointing to have a new product that was bad. I understand it happens from time to time but I lost faith in the brand, returned them and upgraded to MSD. I Installed the MSD and had no problems and was happy with the results. It’s up to you if your willing to take the risk or not.

    Problem after problem

    I installed these, along with a new set of spark plugs, the night I received them. The first thing I noticed was that the boots are quite a bit shorter than the boots on the OEM coils. No problem, a little dielectric grease told me they seemed to be making a connection to the spark plugs. I was excited to take my pony out for a ride. The only problem, I was misfiring all over the place. I drove around for a while and received the much anticipated CEL so that I could figure out which cylinder was missing. I called AM and they sent out a replacement set. I replaced the cylinder that my CEL told me was bad with one of the new ones and cleared the CEL code. Unfortunately, I was still having random misfiring and the power on the car seemed down. I've decided to take them out and put the OEM coils back on and my car is back to running well. I'd recommend looking at another brand.

    Problematic; read review

    I bought this set a couple years ago and installed when I had a few exhaust leaks/tuning issues. Well, I just figured out that they were defective from the get-go. Misfires, lagging response at random, and finally two stopped firing altogether to where I could barely get down the road to the parts store for a temporary replacement. I didn't consider they were bad and after multiple spark plug cleanings, a couple sets of o2 sensors fouled out, and diagnosis (this is a DD car, so I am limited on how much down time I can have with my job), I started thinking these things are the primary cause. When they finally dropped out two cylinders while on the way to the parts store, I replaced two with OEM ones and the idle smoothed out a LOT. I could still hear some missing, slight backfiring upon deceleration, and had some hesitation under WOT. Replacement with a new set altogether (Summit Racing had a set other than these with the upright connector jack and they were blue to match my underhood dress-up style) and she purrs like the day I bought the car. I will not recommend these being there was an entire set defective...not just one or two. They cost me a few hundred dollars in other parts being they kept fouling out plugs, o2 sensors, maybe have caused extra soot in my catalytic converters, and the time I have spent cleaning out my engine from the leftover soot. When they WERE firing at highway speed under cruise control, I was getting a couple mpg out of them, but otherwise they were not worth my money/time.

    Good product. Helps improve firing-much smoother now. Installation is easy but the red stickers, since they're on the same sides, don't look uniform when installed.
