MSD Coil Current Boosters

MSD coil current boosters provide added power to your Ford coil-on-plug engine to support additional horsepower. They also provide a 2-step rev limiter to consistently launch your car off the line. The MSD boosters increase the peak current at the ignition coil and spark energy at the plug gap, making them ideal to support engines with increased cylinder pressure from bumped-up compression ratios, a shot of nitrous, or boosted applications. The 2-step rpm adjustments are made via two rotary switches adjustable from 1,000 to 10,900 rpm, in 100 and 1,000 rpm increments. Just plug them in to the factory wiring and hook up the activation wires as needed and you're set. MSD coil current boosters feature: * Increased current at the ignition coil * Increased spark energy at the spark plug * Built-in 2-step rev limiter for consistent launches and quick 60 ft. times * Quick, easy solution to increase ignition power on Ford modular engines * Factory-style wiring connectors plug directly into stock coils and harness Show Less
