    Rated 5 out of 5 by from Good stuff as usual As always, Jegs and MSD hooked me up. I like the simplicity of the MSD units. Sure, I could have gone with a new grid/digital setup, but for what I do bracket racing, these units work great.

    Will this fit a 97 3.8 mustang?

    Asked by: Karma0024
    This will work if you are using a MSD ignition box with a rev limiter like the 121-6425

    Can I put this on my Ford Focus and does it come with everything I need

    Asked by: Jackie45
    This will only work if you are using an MSD ignition that has a soft touch rev control on it.
