At the drag strip, boosted power is only as reliable as the spark that lights it. When your engine is force fed by a turbocharger, supercharger, or a serious shot of nitrous, cylinder pressures climb fast and demand an ignition system that will not back down. Consistent, high energy spark becomes the difference between a clean pass and a missed opportunity. Built to thrive in these extreme conditions, the MSD DIS-4 Plus High Output Ignition Control is engineered for racers who refuse to compromise.

Delivering up to 170 millijoules of spark energy with 460 to 480 primary volts and 43,000 secondary volts, the MSD DIS-4 Plus High Output Ignition Control is designed to fire dense mixtures under heavy boost. It operates on 10 to 18 volts with a negative ground, supports engine speeds up to 14,000 RPM with 14.4 volts, and draws 10 amps at 10,000 RPM. Features include two adjustable rev limits, an adjustable retard stage, an ignition interrupt circuit, and a diagnostic LED for quick system checks. This black surface mount unit measures 9.5 inches long, 4.5 inches wide, and 2.2 inches high, weighs approximately 3 pounds, includes mounting hardware, and is legal for use on uncontrolled, non emissions controlled vehicles.

Backed by a 1-Year Limited Warranty.
