Ignition Coil


Rated 4.1 out of 5 by 12 reviewers.
Rated 3 out of 5 by Quality part but... Purchased cause they didn't have the one I ordered in stock... The coil was smaller than the original so I had to put in a spacer which scratched the side of it. on further inspection it was not the coil at all that failed but the electronic parts... However now I cannot return the coil cause it's scratched... :-( October 25, 2016
Rated 5 out of 5 by Replacement Product I have not had this item install yet, However I did purchase this ignition coil pack when my truck start jerking under a uphill load and it cured it, the problem seem to have reared it ugly head again but not as bad so instead of trying to figure out which coil my be going bad I elected to change them all along with the spark plug this time. Being Ford have sent me a letter stating I was part of class action suit where this type of plug have been breaking off when trying to remove them I also purchase Z Max gas treatment, along with running several cans of Sea Foam gas treatment and putting high test gas for several months, but as stated earlier these product have not been install yet except for the Z Max. So whish me luck. October 12, 2016
Rated 5 out of 5 by Great performance Awesome buy works as desired September 23, 2016
Rated 5 out of 5 by Just what it needed! Tuned up the Durango, used Accel cap and rotor, NGK platinum plugs, and Taylor 8.2mm wires. Still stuttered a bit in the rain. Checked the coil, found it cracked, decided to turn up the heat a bit and threw in this coil. Quicker starts, better mileage if I keep the loud pedal under control, and it yanks much harder when accelerating. I had to use the wire adapter, but that was easy peasy. A winner all around!

Rated 5 out of 5 by Nice Coils Made a noticeable difference on my 2001 mustang from the stock coils. Easy install with nothing major to take apart. Car starts up instantly with a turn of the key and runs nice and smooth. April 12, 2015
