Description
Fine-tuning your ignition timing across a critical RPM band requires the right tools—and guesswork has no place in precision engine building. This MSD RPM Module Kit gives you five selectable modules spanning 4100-4900 RPM in 200 RPM increments, letting you dial in optimal performance for your specific combination without permanent modifications.
