Overall Feedback:
77% positive
75% praised the high-quality build, while 25% didn't
I installed the coils within 30 minutes after they arrived on time.
If you plan to use these coils long-term, it is advisable to replace the cheap quality boots and coils with better quality ones as they may not last long.
73% liked the compatibility
I compared the new coils with the OEM coils and found that they fit perfectly and even better with a snugger bite on the plug.
I highly recommend these coils to anyone who owns a 4.6L. They work flawlessly on my 07 Lincoln TownCar Signature series.
78% appreciated the durability, though 22% desired more
I suggest using higher quality boots and coils if you are having misfiring problems with these coil packs. I faced the same issue and solved it by using Duralast coil boots and have not faced the issue since then.
In the past 6 months, 3 out of 8 ignition coils have gone bad.
One of our coils died and the company sent a replacement for free.
The coils worked well for about 600 miles and then started to fail.
73% found it easy to install, but 27% struggled
I replaced the ignition coils and added Seafoam to the gas tank, resulting in a significant improvement.
If the boots were not flimsy, I would have given the product 5 out of 5 stars.
72% praised the noise-reducing capabilities, yet 28% didn't
After installing the new coils, all the issues I was having before went away and my vehicle runs flawlessly again. Thanks!
Over time, the power gains slowly subsided.
77% praised the performance
I swapped the coils 4k miles ago and noticed an increase in power, around 15% gain.
