Ok talked with MSD and they said any good quality stock type copper plug should work fine. They said the plugs should not burn up that fast and that the cars set up should be checked. The sparkplug Gap and the rest of the cars parameters should also be checked to be sure your car is running within its parameters. Any good shop/or dealership can help you out with a good diagnostic.

When I installed my MSD ignition box, I had to go with the MSD coil packs. I think they are an adapter of sorts(?). I was told by MSD that platinum plugs will definitely burn up quickly, but that copper (they suggested Champion) would be preferred.

It is pretty rediculous that they design the coils for plugs that were never meant to be in the car. Some people don't enjoy changing plugs every 10,000 miles. As I said before, the stock coils are fine, and seeing that there are plenty of W-Bodies w/L67'* that run 11'* and 12'* with the stock coils I think they supply plenty of spark, and you can use platinum plugs!!!

I also had the MSD coils for a while but they were eating plugs too fast also, now I have stock coils and run AC 41-932 gapped at .55 with no problems, Too bad, they were pretty red though.

Now the Accel coils are completely useless, a month after I put them in I was stranded 10 miles from home when a coil died, they are yellow paperweights.
