Ignition coil MSD or BERU

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.

I recently bought a BERU.

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.

I got MSD Street Fire coils to replace mine and its been 4 months so far and they're running strong.

I have used the blaster w a stock icm (the inductive version) and also with a 6al (cdi version). Both worked well over for 400whp with a stock dizzy.

I have an MSD blaster 2 coil on my 93 fox and it works great. I went with this coil for convenience (bought at a FLAPS when my stock coil died) rather than performance, so unsure if there are any gains to be had (doubtful).

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.

I ran a Blaster 2 on my old car for a bit. Idle was a little smoother, but it was probably because the coil on it was crap. No real performance gains expected.

I've replaced 4 of the 6 packs over the last three or so years. All but one actually broke in two when trying to remove them, leaving the bottom half on the spark plug!! I suspect water ingress (not sure how with all that plastic) as the coil packs all showed signs of corrosion.
