The coil kit at my local auto parts store is $130 and I was hesitant to buy the $52 kit but they fit perfectly and ready to go to my 4.7 Durango from 2003 At the start I felt a difference. faster starting, smoother idling and better acceleration. Super fast shipping was a bonus. Haven't driven it long enough to test the difference in MPG, but the immediate improvement in truck performance made me very happy. BTW, I'm not sure if it's because the old ones were stretched at 130k and were a bit looser than these, but I had to press on them pretty hard to get them to snap into place. forks, but the click of that click made sure they were snug against the fork! I definitely recommend them! TO UPDATE. Well, after 6 days of driving and about 200 miles with these new coils, my truck started to skip, but not enough to cause a CEL. Every 2-4 seconds he will have a very noticeable "tremor". So I went back there and took out a coil, replaced the new one with the old one, started it and let it run and after doing this with each coil I found that this was a new coil that I put in the second stuck cylinder. It works like a charm with the old coil in cylinder 2 and the remaining cylinders with new coils. So that tells me I either have a bad coil or it won't last for a while. The time will show. Now I have to buy a new coil somewhere so they are all new. It would be great if they sent me a replacement, but the hassle of finding out if they're coming is just something I'm not willing to invest in. For $52, is this closer to what I'm expecting? UPDATE 2 - Well after less than 500 miles I had to take them ALL out. Misfires, judder and rough idle. I backed up all of my original 130,000 mile coils just to make sure it's nothing but coils. My old ones ran better than these! What a waste of $52 and time! Went to my local chain parts store and got a $129 kit with warranty, now my truck runs like new. Save time and money and start with the best. I originally gave that 5 stars but am now changing it to one. TERRIBLE COILS! send her back Will change the star rating if you are satisfied with the refund.
