Kevin2 MSD does stand behind their products for multi reasons. They also want the bad parts back for R&D. I don't know which coil you are running. I have to ask you about how the coil is mounted and if it's a
oil filled old style design? Mounting
oil filled can and will over time, horizontial on a motor will go bad. Vibration heats the
oil in the canister and turns it to foam and the heat can cause an explosion. I have blown 2 on my CJ. I know it's not the original way or location. Also only the lower half of the coils are being cooled by the oil and the upper windings are being cooked. Last coil I blew had the dry coil windings blue and black and the lower part of the coil was clean coated windings. Gald the car is fixed Rick
