Review on ๐Ÿ’ฅ Boost the Power: Unleash Performance with MSD Ignition 6425 6AL Control by Carlos Abood

Revainrating 5 out of 5

Worked perfectly, best in spares

My vintage 1973 Mach 1 Mustang already had an MSD ignition system that worked great. But it had a 6425 6 Ignition Control Module and I wanted to be able to limit the engine speed. The 6AL block was plugged directly into the same connector that was previously plugged into the "6" conditional module with no rev limiter function. I "tested" the 6AL and found that it works great keeping the engine RPM within the limits I set for the modules.

Pros
  • Easy to read control panel
Cons
  • Negative present
