Increase The Voltage Output Of Your Coil-On-Plug Ignition System

The SparkMAX system from JMS is a splice-in voltage booster for your coil-on-plug ignition system. This voltage boost allows you to run your vehicle with a wider spark plug gap. The wider gap allows the engine to run more efficiently by causing a larger spark, and igniting more fuel every spark. This also helps to prevent spark plug blow out. With the optional voltage power adjustment knob, you the user can adjust the voltage output "on-the-fly" to quickly and precisely tune the vehicle's voltage.
