AEM’s digital multi-channel Twin-Fire Ignition is the lightest, smallest and most cost effective ignition module on the market. This unit is available in four- and eight-channel configurations, works with O.E.M. coil-on-plug and distributed spark systems, and is ideal for applications that utilize aftermarket stand-alone engine management systems.

Our Twin Fire Ignition module is the only capacitive discharge ignition system available with dual capacitors. This enables the Twin-Fire to produce more spark energy and voltage per spark than any other available capacitive discharge ignition unit. AEM’s exclusive Twin-Cap technology stores the energy for two distinct spark events and allows for full energy for each individual plug, including high-rpm V8s, and even on rotary engines utilizing separate leading and trailing ignition maps.
