HKS DLI TYPE 2 IGNITION AMPLIFIER SUPRA 2J FOR HKS DLI TYPE 2 YOU WILL REQUIRE THE DLI HARNESS ALSO LISTED ON THIS SECTION... The Twin Power ignition amplifier integrates Capacity Discharge Ignition (CDI) and transistor ignition technology to offer improved throttle response and smoother engine performance by providing optimal spark duration and maximum voltage output. The CDI technology provides maximum voltage by transferring all stored energy in the capacitor to the ignition coil so the ignition current can build quickly, making the Twin Power very effective at higher revs where a normal spark would diminish. The strong, rapid spark prevents high rpm ignition misfire that reduces peak power. The transistorised method generates high voltage by using transistors to cut off current to the coil, allowing a long energy discharge. This longer spark duration allows the Twin Power to improve lower RPM throttle response and torque. The Twin Power produces a spark output that is typically 1.5-2.5 stronger than a stock ignition system and consumes about 35% less power than other ignition amplifiers.
