MSD 6a ignition

[Cadinrfv]

I have a 93 GAGT. I am thinking about installing the MSD 6a ignition. 8.5mm wires, and Bosch Platinum+4

Anyone have any experience with them, and which coil do i use.

The stock is has the 3coil pack.


Thanks

not sure about those coils, MSD makes good stuff from what I've seen/heard. Those wires would be great too, but try to stay away from those Platinum plugs.
You will be dissapionted when you hav to replace them in a few months. They burn up fast, and I hav seen the electrode in the center fall out, inside the chamber. not good!

The coils are good along with the wires. But like xeroinfinity states the plugs are junk. Stay with iridium or other plugs. Bosch +4 and most Bosch plugs are junk, in my opinion especially in GM engines.

I read elsewhere to stay away from the iridium plugs, which was why o was leaning toward the +4's .

Autolite double platinums were my next choice.

Called MSD today, they must be closed observing the New Year holiday. The automated system kept me on hold for over an hour.

After further research, the 6a is no good as the 93 GAGT is a distributorless system.

Upgrades would be as follows for MSD

MSD 62152

MSD 8224 x3

So far Summit Racing has the best prices.
If anyone can find cheaper please post.
