    Why are there so many 44 promag coils for sale. Do they get week? I read one add where they changed out coils every pass!

    Black coil

    I've been running an old MSD 44 "black" coil for 4 years, never have had to grab the spare out of the trailer. Probably just jinxed myself......

    From the ProMag website.

    "Eventually coil usage will degrade coil life or performance, unfortunately translating this into a number of passes, races or years is difficult to determine."
