Reviews of MSD ignition coil

Since reinstalling the stock cam and ECU chip in my motor all has been running very well. Even with the raised 10.7:1 compression, the car has zero issues. For the longest time, I've had my plugs gapped to .032". I'm running an MSD Blaster SS coil and Magnacor 8.5mm wires. I was "told" to run a colder gap because the coil is too much for the stock (.024") plug gap. So on Sunday, I put the gap back to 24thou to see how it ran on my Monday commute. It honestly felt bad. Getting on it in a higher gear at lower rpms, I could feel what felt like the ignition being cut back by the knock sensor. It felt like it was missing briefly till the knock sensor retarded the ignition. There was slight power loss as well. It just felt like it ran poor, overall. So last night I put the gap back to 32thou. The ride today felt like it did before I messed with it. None of that iffy feel, just power with no complaints. So, with an aftermarket coil anyway, I would suggest a wider gap on your plugs. Motor runs way better IMHO.

My car now runs smoother, starts quicker, and revs quicker & I have a cool red coil under my hood.

mine was stubbling like crazy too and it was the coil... i used an msd 8202 and wired it up to my ignition module... problem solved for $45

i had a MSD 6a with blaster 2 coil installed on my turbo ABA. it did drive much better/smother. the hardest part was to take apart the stock coil. but after that it was quick.

the car does seem to idle smoother but I can't really make a valid comparision since I installed a new dist. rotor along w/ the coil. The real reason I chose this coil is because it was about 60-70 bucks cheaper than the oem unit and who knows... maybe the hotter spark will help out.

Definitely gave it more spark because my car idled higher and the inside of my coil wire where it connected to MSD had all types of bright green/blue corrosion starting. Definitely noticed a major difference in idle when I took the MSD out. Car was a lot quieter and idle was smoother.

i believe the hotter spark and the MSD system created a smoother running car. i switched back and forth between the stock coil and the MSD. while the stock coil did work, the MSD made the car run smoother and didn't break up at higher boost levels. the MSD blaster 2 coil is a lot cheaper than the stock coil also. no more cracked coil housings.

I burned out 2 jacobs coils using the Bosch ICM with CIS before I put in a MSD blaster that held up fine. The Jacobs would get burning hot to the touch, I returned them to autozone.

MSDs are good coils and are meant for racing and not daily abuse. I will guarantee that after time it will crack due to the engine heat, use, etc. May not be for years, but eventually it will.

anyway, my friend put one in his Toyota truck and it smoothed out his idle and boosted midrange
