International Scout owners, your day is here! Davis Unified Ignition now offers International D.U.I. distributors--compact, one-piece ignition systems--for your International V8 and 4-cylinder engines. These D.U.I. distributors are designed to be virtually water, mud, and vibration-proof, with the electronic components protected inside of the distributors. And setup is easy--run one 12 V hot wire to the D.U.I.s, and you are ready to go! A tach hookup is also provided. They feature a 50,000 V coil and a high-output Dyna Module that work together to produce a longer duration spark, allowing the spark plug gaps to be opened up to a whopping .055 in. The larger spark plug gap burns the fuel mixture more completely, giving you more power. A hotter spark also keeps your plugs cleaner longer. Every D.U.I. is hand-assembled to exact tolerances--there is no mass-production. The units are calibrated on a distributor machine with a super-smooth advance curve, providing you with instant throttle response and more power, while eliminating damaging detonation. There will be no trial and error for you--the advance curve is already dialed in. Built for durability, they have both an upper and lower oil-impregnated bushing and include a heavy-duty cap and rotor with solid brass terminals in your choice of red, black, blue, yellow, or clear. Install added performance for your Scout with Performance Distributors International D.U.I. distributors.

Holley EFI Smart Coils are a bolt-in ignition upgrade for your late model HEMI or Coyote engine. Here's the difference over a stock coil: they produce more spark energy while consuming less power without sacrificing voltage output. This means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder while using less power from your electrical system. Smart Coils are available individually or in sets of 8. * For Coyote or Hemi combinations currently using Holley EFI or Terminator X, use Smart Coil Ignition Harnesses 558-312 and Coil Extension Harnesses 558-326 for a plug-and-play solution. * For new Holley EFI installations on Coyote engines, use with Holley EFI Coyote TI-VCT Main Harness for Smart Coils 558-122 and Smart Coil Ignition Harness 558-312 for a plug-and-play solution. Features: * Direct bolt-on to factory valve covers * Same wiring pinout as other IGN-1A coils for easy plug-in upgrades (Will not work with factory wiring) * More spark energy than any other smart coil on the market for maximum fuel burn during combustion sequence * Low current draw means less demand on the electrical and charging system * Built-in ignitor for compatibility with Holley EFI and many other aftermarket ECUs * Maximum operating voltage of 18 V—for compatibility with both 12 V and 16 V electrical systems found in many performance/race applications

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.
