RE: aftermarket coil on plug

I think that would be wise. Try googling both and see how many problems people had with GMS cops.

I'm leaning toward MSD, since they are known for they're ignition systems.

RE: aftermarket coil on plug

I had the gms' and I had to put the stock ones back in because on of theirs went out. It was kind of scarry when it went out because it started stumbling.

They kick *** until you burn one out. I had the GMS ones and four of them burnt out.
I have the MSD COPs now they rock! Big improvement over stock coils.

Ya I thought they made it idle and run smoother. There was also a noticable gain in the upper rpms.

Could you see any real gains with them? I've looked at the COPS too but wasn't willing to experiment with GMS. I'd prefer the MSD with Accel being 2nd and GMS being a very distant 3rd.
