MSD Street Fire 55128 Ignition Coils - Black - 8-Pack

Works great wish I would have replaced them all sooner instead of 1 here 1 there bs

These are totally worth it. We tried to cheap out before and get that $50+/- set that is on here and they did work. Well, at least they worked better than the dead coils we had before. But there was still always a slight misfire issue. Eventually we had enough of it and spent the few extra bucks and got these. Night and Day difference. Visually, you can see these produce a much more intense spark. Installed, the idle is smoother, and the power seems to come on better. Prior to these, my truck would have a little "pop" or as my girlfriend called it "a bubble" in the idle, and it just felt a little tired when accelerating. These coils gave it a much better feel and smoothed things out. In my book, totally worth it.

They look and work like OEM so far. I have been told that these China-made coils will go belly up in a year or so, but we shall see. I generally prefer OEM, but coils are pretty pricy and 4.6 Fords have issues with the COP design, so I will try these cheapie coils for now and see what happens. As I said, OEM fit and OEM performance so far.

First off packaging was very good. Was shipped fast and correct for application. Instructions were clear and concise. Installed with new plugs and all is good so far. How they will hold up is yet to be known but quality based on looks alone of the coils seems to be very good. Cured the misfire and truck runs as it should now. Went with the MSD name and paid more for it because I didn't trust what I would get from some others at much lower prices. However, these are made in China also but I'm hoping the MSD quality control will be superior to the cheapo stuff. Time will tell I guess. Still way cheaper than Motorcraft that unless you are very careful, may or may not be counterfeit anyway.

Replaced a hodgepodge of coils in my Crown Vic along with a new set of Motorcraft plugs. Car ran smoother.Will see how they last long term.

Price can't be beat... going to a parts store you're paying almost $300 for them and they are special order from the factory. Easy install on my 2004 Mustang GT , and it sounds better and definitely runs better with the upgraded coils.

6 coils are still doing great about a year after purchase, 1 cracked and another just stopped working

These were far less expensive than OEM parts and seem to be of great quality. They have been running strong for 3 months now. I will say that for a green shade-tree mechanic, changing these out on my 2002 F-150 was a difficult 2-day ordeal that required purchasing new tools and several bandaids.
