Holley Distributorless Ignition

Holley's Distributorless Ignition System (DIS) components are manufactured from high quality materials for strength & durability. The 58 tooth wheel provides a very accurate crankshaft signal and offers many advantages over a conventional distributor/ignition box including:

Improved starting and idle quality

More spark energy - especially important when using power adders to maximize horsepower

Cleaner Emissions

System Longevity - No Moving Parts

Tuning Simplicity and Accuracy

NOTE: It will be necessary to move any engine accessories about 1/8" to accommodate the spacing the trigger wheel adds.
