Dynatek Twin Fire® coils are designed to be used with single-fire microprocessor equipped (electronic advance) ignitions. Dyna’s Twin Fire coils feature the same fast rise times, high energy and 30,000+ volts output as their other popular coils. The advantage of using a Twin Fire coil is it is actually two coils in a single housing, designed to bolt to stock mounts and simplify coil mounting in single-fire applications. Each outlet operates independently of the other (front cylinder, rear cylinder). A four outlet model is also available for dual plug, single-fire use. The 4-tower coils are slightly larger than the 2-tower coils; stock coil covers will not fit without an optional coil cover bracket. These coils are NOT designed to be used with Dyna ‘S’ or other mechanical advance ignitions. Not for use on Twin Cam® applications except where noted.
