MSD Street Fire 55138 Ignition Coils - Black - 8-Pack

Product fit great and performed as it should. These, along with new plugs fixed my sporadic miss. Seems like a quality product. Time will tell.

The media could not be loaded.  They look Awesome, work flawlessly "so far" highly recommend !!

I've always found MSD products to be trustworthy and these coils haven't let me down. Great price compared to the OEM coils. I will definitely buy again when needed

All good and running

I had planned to wait several weeks to write this review, but these coils have made such an improvement in my 2006 Lincoln Navigator, I was too excited to wait.... This car developed a "clunk" into overdrive a few years ago. I was convinced the transmission was on its way out. A few months ago, my car began shuddering while in overdrive, particularly on slight uphill grades. Several members of online forums suggested this shuddering was misfiring due to bad coils or plugs, and they were exactly right. Both of the issues that I thought were transmission related stemmed from bad coils. My Navigator is now a smooth riding machine.I should also note that I was initially skeptical about non-OEM coils. I decided to purchase MSD coils because they seemed to have better reviews than the Motorcraft coils, and I'm very glad that I did.I will update this review if any of the coils fail. Otherwise, you can assume all eight coils are still working properly.

My 2007 F150 had this slight miss when running 45 to 55 mph under load. I changed plugs about a year ago and it fixed it for a while then it came back. When I started looking for coil packs I didn’t even know MSD made them for my truck. I grew up going drag racing as a young boy and knew MSD made a good productThe coil packs are fairly easy to install. The two closest to the firewall are a little bit of a pain but worth the effort instead of a shop charging me way to much for doing it. I could tell just by the little click when installing the new ones my truck was going to do much better. The old ones had no tension on the little spring that slides over the top of the spark plug. Great product and would recommend

Great product they have worked flawless for a little over 100,000 miles. Only replacement I would use other than motorcraft.

Just perfect

Name brand product for a great price. Runs and fits as well as OEM.
