MSD 6430 6ALN Ignition Control Module with Soft Touch Rev Control

The MSD 6430 6ALN Ignition Control is a race-grade, multiple spark capacitive discharge ignition box engineered for high-performance and competition applications. Featuring a clear plastic base plate for quick and easy tech inspection, the 6ALN is built to meet the demands of sanctioned racing, including mandatory NASCAR requirements thanks to its 6-pin Weathertight connector.

This ignition control operates on 12 to 18 volt electrical systems, delivers a massive 470 volts of primary output to the coil, and fires multiple sparks throughout 20 degrees of crankshaft rotation at every combustion event. With 110 millijoules of spark energy sustained all the way up to 15,000 RPM, the 6ALN ensures complete combustion across the full RPM range.
