Performance Distributors’ Deluxe DUI for street and/or strip applications encompasses four features in one Davis Unified Ignition package.

First, the new Cross-Fire Cap allows you to route your plug wires neatly on each cylinder bank, providing the same 50,000V DUI Coil and high dwell Dyna-Module as you do with their standard Street/Strip DUI. Available only in a black cap, it can be painted to match any engine compartment’s theme, also allowing the sleek look of your plug wires to be well organized.

Second is the Adjustable Slip Collar with 7/8 inch of adjustability. It’s great for decked heads or a milled block, which changes the distance between where your distributor rests on your intake and where it meshes with your cam gear.

Third, a Carbon Ultra-Poly composite gear is used, making it compatible with any camshaft (solid, hydraulic, factory roller, or steel billet roller cam), which  solves wear problem.

Every DUI is calibrated on a distributor machine, providing a smooth advance curve, instant throttle response, and more power. The mechanical advance works in conjunction with the vacuum advance, preventing engine damaging detonation.
