Product Information
MSD DIS-4 PLUS IGNITION BOX
MSD's DIS-4 Ignition Control is designed for engines with coil pack, waste spark ignition systems and is capable of firing up to four coil packs (or even four individual coils). Each Control delivers full power Capacitive Discharge sparks from idle through racing rpm. Below 3,000 rpm there is a series of multiple sparks that last for up to 20 deg. of crankshaft rotation to improve idle, starting and throttle response. The adjustable features of the DIS Ignition includes an over-rev limiter and the holeshot rev limit. Also, there is a step retard that can be wired directly to a nitrous system or switch for activation! These are adjustable with rotary dials.
- Two Step Rev ControlStep Retard

From ignitions to distributors, starters to coils, from spark plugs to plug wires, there’s an MSD product to help you get the most out of your engine.
