Davis Unified Ignition Ford Street/Strip D.U.I. Distributors

Davis United Ignition Ford Street/Strip D.U.I. distributors are performance replacements for your daily driver, street rod, or off-road vehicle. Rated at up to 7,000 rpm, these simple all-in-one ignition systems have the coil inside the cap and the module inside of the distributor; drop them in, run one 12 V wire, and you're off with 50,000 V of pure spark energy! The high-voltage coil allows for wider spark plug gaps, while the increased dwell in the D.U.I. Dyna-Module produces a hotter spark to deliver the most complete burn of your fuel mixture. Street/Strip D.U.I. distributors are tuned for several Ford motor applications, creating a super-smooth advance curve and eliminating engine damage. They're built tough with oil-impregnated upper and lower bronze bushings for shaft stability, accurate trigger signals, and years of trouble-free service. D.U.I. caps are offered in red, yellow, black, blue, and clear—so you can watch the sparks fly! Give your ride more power, crisper throttle response, and more low-end torque with a Ford Street/Strip D.U.I. (Davis Unified Ignition) distributor from Performance Distributors.

Davis Unified Ignition LiveWires

You need a good spark to make good energy and power. Davis Unified Ignitions LiveWires are spark plug wires that deliver the spark that you need for the energy that you want. Made with space-age, non-flammable, heat-treated glass braid, LiveWires provide heat protection up to 1,400 degrees F and offer excellent resistance to moisture and chemicals. They feature a spiral-core stainless steel wire wrapped around a magnetic core, offering extremely low-ohm resistance for optimum spark travel. And there is no radio interference, enabling them to work well with delay boxes and stutter boxes. LiveWires have a durable silicone jacket and insulation with heat-shrink applied between the boot and sleeving to keep dirt and moisture away from the wire terminals. Another excellent feature of these custom-fit, ready-to-go wires is that they're foolproof. Each wire is numbered on both ends for the correct cylinder—making installation, removal, and reinstallation hassle-free. LiveWires are available in eye-catching colors to match the sparking power that they provide. Quality wires are more than just wire and coverings. Make sure that you're wired to fire with LiveWires from Davis Unified Ignition and Performance Distributors.

Davis Unified Ignition Ford Duraspark Distributors

Davis Unified Ignition Ford Duraspark distributors are high performance units for those who want a completely stock appearing or factory-style electronic distributor. They are custom-calibrated on a distributor machine and blueprinted to provide maximum power, torque, and instant throttle response. DUI tunes the centrifugal advance using information about the vehicle and engine such as cam duration and lift, carburetor size, compression ratio, vehicle weight, and fuel octane. A super smooth advance curve assures excellent performance and mileage. The vacuum advance is calibrated for maximum fuel economy and light throttle ping is eliminated. The weak factory center bushing is replaced with a full-length bronze oil-impregnated bushing to provide increased durability and cure top-end timing fluctuation, a common problem in these distributors. Davis Unified Ignition Ford Duraspark distributors can be used for everything from everyday street use to all-out racing. They are capable of up to 10,000 rpm with a DUI Dyna-Module and Inferno Coil kit (with other modules and coils, rpm ability is not guaranteed). They come with a brass terminal cap and rotor in your choice of cap colors.

Davis Unified Ignition SOS Ignition Coil Packs

Davis Unified Ignition SOS ignition coil packs feature advanced technology to pack more electrifying voltage into them for pure ignition performance. The SOS (Sultans of Spark) ignition coils are designed with increased windings to boost spark output up to 40,000 V! That is a 60 percent increase in spark energy over the 25,000 V produced by the stock ignition coils. The higher voltage, along with an increased spark duration, allows spark plug gaps to be opened up. The larger gap exposes a hotter spark in the combustion chamber for an increased burn of the fuel mixture, resulting in more horsepower and better fuel economy. Davis Unified Ignition SOS ignition coil packs also provide quicker starting, smoother idle, and excellent throttle response. They are direct replacements for the factory coil packs and do not require any special modifications for installation.
