I was stoked on getting these coils installed and thinking everything will go well. Unfortunately things started to go downhill once I noticed the Allen screws on the top plates didn't fit in all the way. As you can see in the pic below, I couldn't install all 6 Allen screws that it came with--I only did the 4. Not only that, but you can also see that two of them are bacailly engraved into the sidewall. Other than that, these coils are alright. They handle pretty fair for daily driving. I've also noticed a little chirping sound it makes every time I go over a bump.
