MINI Cooper S MSD Coil Pack

Well this was cheaper than any stock unit I saw, and I had the dreaded #3 lead problem. Installed this along with the MSD wires, haven't noticed any difference in performance or economy, but there is the piece of mind component. The only issue I had was that the little stock rubber grommets that go on top near the bolt head, two of them split when tightening the bolt even a little, they were too brittle. It'd be nice if 4 new grommets could be included with this coilpack!

get one of these! Found my #3 connect was also turning so I swapped it out with one of these over a year ago.. No problems since! Only reason I gave it 4/5 stars was simply because I didn't really see any performance increase from this or the new plugs and wires...but I'm sure it was a good investment.

While browsing the site I read about the possible build up of rust on #3 lead on the coilpack. I checked and discovered that 3 out of 4 terminals were showing issues and ordered the MSD pack right away. Installation requires only a 10mm socket and takes maybe 10 minutes. The new pack fits perfectly and stands out nicely in the engine bay. The difference has been instant. Cold starting is much better (especially as I live in a cold part of the USA) and some odd "pinking" noises when accelerating uphill in a high gear have all but gone. Idling is perfect without a hint of roughness and the engine generally seems smoother. If your Mini is more than three years old and you drive more than 12,000 miles a year, one of these babies is a must!

After looking at your website I immediatly went and checked my coilpak and sure enough you were right, #3 was rusted and so were all the others to som e degree. Bought the MSD from you site and boy what a difference, milage was increased as well as horsepower. Seat of the pants felet like at lease 5 horsepower. Thanks Madness!

I just replaced my OEM coil with the MSD, which looks like it was made on the same machine as OEM, but has brass terminals, which are more costly and better conductors than the OEM plated steel connectors. I replaced it because one of the connectors was showing symptoms of arcing - a black spot on the plated connector. The result was a smoother-sounding engine from 6K to 7200 rpm. I don't know that it got any more power from the MSD coil, but removing the arcing residue clearly resulted in better high-rpm ignition. I was not expecting a performance improvement, but I got one, or at least recovered performance lost to arcing at the coil. The "corrosion" that most have described appears to me actually be electro-erosion, due to arcing at the connector., The black stuff is vaporized metal and metal oxides from the plating and the steel terminals. Chemical corrosion would be whitish or rusty-looking. I mention this because if you show symptoms of arcing on the coil terminal, there will be at least as much black stuff inside the socket on the spark plug wire. This gunk is high-resistance, and can cause future arcing, so... When you replace a coil that shows arcing, use some Deoxit and a q-tip and clean out the connectors on the wires, or buy new wires, or you will probably be replacing the coil or wires again in the near future.
