ENA Ignition Coil Pack V8 5.7 6.1 6.4 Compatible with Chrysler Dodge Ram Jeep Aspen 300 Challenger Charger Durango Magnum Commander Grand Cherokee 2005-2019 Coils for UF504 C56029129AA, Set of 8 Red

140k miles on a 5.7 Hemi and lost power, rough idle and Check engine light came on. I was really worried about the lifter issues with these motors. I was thinking I was going to need a rebuild. These replacement coils did the job. Coil change and did the spark plugs while I was there. Awesome.My engine is more responsive and runs better than it has in years. I couldn't be happier with the results.On a different note, I did read a bunch of the reviews about people breaking them during installation. I was very careful when torqueing them down to avoid any problems. I recommend the same.thing.

I would have given five stars on the install, but on a Hemi engine two of them are not easily installed. Had them on for over 500 miles and noticed better gas mileage.

Worked how it's supposed to and seemed pretty durable. Perfect easy fit. Comes with dielectric grease which is nice, but I'd recommend picking up a tube if you don't already have one.

I just changed the plugs and replaced the original packs with these. So far, they fit well, no issues installing them and working well (2 weeks). I will try to update as I put more miles on them.

Direct fit no misfire car runs excellent
