I've had mine for 4 years with no issues. In fact it was arcing out of a cut in the wire across 1.5 inches of empty space to ground in dry air conditions. (Don't worry I already installed new plug wires last weekend.)I'd save my money, the MSD coils don't seem to last long enough on our cars to be considered an upgrade, imho.
Sure. Unless it stops working good. This has happened to quite a few people. What seems to have an even better track record is the OEM unit. Is there a reason beyond the cool, shiny red paintjob that you prefer the MSD to an OEM unit? The OEM unit can be rattle canned that same cool, shiny red too.Is the MSD ignition coil good for 94 impala ss?
+1 with leadfoot, I doubt the coil is the culprit behind the flashing but if you have another one handy, you can give it a shot.I just got a msd coil and think its to powerful because my spark plug wires are flashing by the plugs when you look at them at night. My msd wires are brand new and so are my ac delco platinum plugs.
