Coil Pack High Voltage Output

These coils output up to 80,000 volts, significantly improving horsepower, throttle response, and overall performance. They are designed as a direct, bolt-on replacement for your stock coils, requiring no modifications for installation. Featuring patented isolator rings, these Pro Series Xtreme coil packs offer 0 ohm resistance and prevent RFI/EMI interference, ensuring a clean and powerful spark. They are built to withstand demanding applications, including supercharged, turbocharged, and high-level nitrous setups, preventing the spark blowout often experienced with weaker coils.
