Summit Racing™ Ford Mod Motor Coil-On-Plug Ignition Coils

Your Ford is built to eat asphalt and clear its pipes with compacts. Summit Racing™ Ford Mod Motor coil-on-plug ignition coils are engineered to fuel the powerful combustion needed to unleash its inner potential. We use pure copper wire, rare earth magnets, and a custom primary and secondary wind, to provide 40 percent more voltage and 20 percent more energy (mj) from a stock-sized coil housing. They fit in the stock location, making changing these coils as easy as possible. If you're running at increased PSI with a supercharger, turbocharger, nitrous, or are burning E85, you need the hottest and strongest spark possible to burn your fuel. With the increased voltage and energy output values, your cylinders will get the spark they need to maximize fuel burn! These ignition coils are available in a variety of power options; order the model recommended for your vehicle.

This allowed NGK engineers to reduce the voltage requirement for a spark. Iridium IX plugs are available in more than a hundred configurations for universal and vehicle-specific applications.
