My MSD6M box is bad.Dose it pay and would it be wise to replace the box and revlimiter with a new and updated unit, like a MSD6M2L?


I just missed a MSD6M box on E-Bay for 41.00$

We run the NASCAR box. Same as marine just seem to be sturdier and cheaper. Its the "n" box. Msd will admit its the same.
