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.

Davis Unified Ignition Dodge Tri-Power Distributors

Performance Distributors Dodge Tri-Power ignition systems offer high performance for small block, big block, and Slant-Six Chrysler engines that cannot fit D.U.I. distributors. The first part of this triple threat is the Dyna-Modules. They mount externally to the distributor housing and have more electronic dwell than stock—longer coil saturation, hotter spark. Secondly, the Inferno coil, also mounted externally, allows you to open up your plug gaps for extra fire to burn fuel more completely and provide more power. The combination of high-voltage coil and high-dwell module will impress you with quicker starting, smoother idle, and better performance—up to 7,500 rpm! The final part is calibration. Tri-Power distributors are tuned based on cam duration and lift, compression ratio, fuel octane, and vehicle weight of each of the specific applications available. A super-smooth advance curve eliminates engine-damaging detonation, provides instant throttle response, and produces maximum power throughout your entire rpm range. Choose a winner that has it all. Feel the difference with Dodge Tri-Power ignition systems from Performance Distributors. Select the model for your application needs.
