Davis Unified Ignition (D.U.I.) GM Street/Strip Distributor With Cross-Fire Cap offers the best of both worlds! If you are wanting all the performance of D.U.I.'s high voltage coil, high dwell module and performance advance curve but also with the sleek look of your plug wires being organized, this is the setup for you. This distributor and cross-fire cap combo keeps your engine bay clean, and plug wires neat; perfect for show cars, weekend race cars or an everyday driver. Davis Unified Ignition developed a unique design where left engine bank plug wires exit on the left side of the distributor, as does the right. This eliminates any wire crossing, preventing arcing from one wire to the next. The cross-fire distributor cap is only available in black but can be painted to match any engine compartments theme.
