Performance Distributors D.U.I. nylon shims may be necessary to protect the cam and distributor gears from irregular wear--especially if your engine has had the block and heads milled. If that's the case, then the distributor may sit too far down in the motor, which will "bottom out" the distributor on the oil pump. This is a bad situation which puts the gears in a bind and will cause irregular wear and destruction to the teeth of the gears. These high-impact nylon shims are designed to fit between the intake and distributor gasket. Installing a shim with the correct thickness will allow the gears to mesh properly and can prevent costly repairs down the road.

Davis Unified Ignition now offers the Crossfire Street/Strip coils with the Crossfire distributor cap. This distributor and Crossfire cap combo keeps your engine bay clean, and plug wires neat, which is perfect for show cars, weekend race cars or an everyday driver. The Crossfire D.U.I. caps are designed to route the plug wires in numerical order to each side of the engine by corresponding all odd cylinders to the left side of the cap and all even cylinders to the right side. This eliminates any wire crossing, preventing arcing from one wire to the next. The Crossfire distributor cap is only available in a black finish but can be painted to match your engine compartment theme. And as with the standard Street/Strip D.U.I. you get the same high-voltage coil, high-dwell module, and performance advance curve—but with the sleek look of your plug wires being well-organized.

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.
