Review on Straight Ignition Lincoln Mercury Compatible by Christopher Gonzalez

I have a 2006 Ford F-150 that when accelerating slowly around 45 or 50 mph jerked. I changed the spark plug about 30,000 miles ago so I decided to try a new coil. Considering the cost of this set I figured I wouldn't be wrong. That was the first time I changed coils. It took me about an hour and a half with a few minutes to watch the YouTube video but I managed. The hardest part was getting to the coils on the back with my large hands and small work surface. I am happy to report that my truck is now running smoothly with no stutters. I am very happy with the results. Update: After about 3 weeks of use I already had an ignition coil failure. I was driving at freeway speed and noticed my truck starting to disappear. I finally checked the codes and found that cylinder 1 was missing. I had to buy an ignition coil at my local auto parts store which actually cost more than all of those 8 coils combined. Problem solved. I have to change my rating to 1 star. Update: I contacted the seller and he sent me a replacement ignition coil. At least I have a replacement now. A few months have passed since the coils were installed. All other 7 previously installed ignition coils still work great. Rating upgrade to 3 stars.
