Ignition coil MSD or Duralast

I’ve always had good luck with MSD coils. I’ve had them on MULTIPLE vehicles.

I’ve used Duralast coil on a bmw with no issue and lasted over 60k when I sold the car. It was identical to the Delphi coil.

I purchased the MSD coil upgrade kit, swapped out the coil pack, new spark plugs / wires, fresh oil / filter. Fired her up and she purred like a kitten.

You can also spring for the MSD coil, about twice as much but the boots are attached better I think, where the OEM part might have the boots rip off or the springs get caught up.

Have 2/4 duralast coils on my car and about 50k miles later they’re still fine

I replaced the coil with a MSD high performance which was actually cheaper than any other brand, and had significantly better boots on it to keep the water problem from happening again. Haven’t had an issue in 2 years.

Duralast is a hit or miss kinda deal. It’s equivalent to oem. The good thing about it is you can swap them out for new ones if it ever fails. The bad thing is they either fail in a very short period of time or last for a very long time there’s no in between.

So I replaced the coils with MSD packs, and tossed in fresh plugs, even though the old ones were less than 10k miles in. This seemed to fix the issue for a while, but it ended up coming back.

About 2 months ago I had a cylinder 4 misfire while on the interstate so I pulled over got it towed and replaced all the ignition coils(duralast) and spark plugs. It fixed the problem and I went on my merry way. Well now today I am currently on the side on the road waiting for a tow truck and once again got the p0304 code(cylinder 4 misfire). When I replaced the coils last time the coil in Cylinder 4 looked like it had melted. I haven’t been able to look at it now but what could be the cause for that? Do I have an underlying issue somewhere else or did cheap parts just bite me in the ass like they always do?

Used them on my 17’ Wrx premium. Worst decision i ever made. Motor started misfiring. Drove easy until i fount a replacement. Motor blew before i could swap them out 2 weeks later.
