Brand: MSD Ignition
These plug-in RPM modules are used to set the rev limiter on the MSD 6AL Ignition System with Rev Limiter (formerly Part No. 1321) and the MSD Soft Touch Rev Control (formerly Part No. 1245). Although we no longer carry the limiters, we still offer these modules to retrofit existing setups. Each kit spans 800 RPM and includes five modules in 200 RPM increments.
