MSD DIS-4 Plus Higher Output Ignition Control

For full bred drag race engines running high boost pressures from turbos, blowers or nitrous we offer a Higher Output version of the DIS Ignition Controls. The DIS Plus HO Ignitions produce an incredible 170 millijoules of spark energy with 470 primary volts. This increased output will light up fuel mixtures even under extreme cylinder pressures.
The DIS-HO boxes are not CARB approved and are designed for drag racing applications only.
