The CDI method (capacity discharge ignition) provides maximum voltage by transferring all stored energy in the capacitor to the ignition coil so that the ignition current can buildup quickly, thus making the Twin Power very effective in the higher revs where a normal spark would tend to diminish.  This strong rapid spark prevents the high rpm ignition miss that reduces peak power.  The transistorized method generates high voltage by using transistors to cut off current to the coil, thus allowing for a long energy discharge.  This longer spark duration allows the Twin Power to improve lower RPM throttle response and torque.

Each compact and attractive Twin power unit is constructed of durable anodized aluminum and sealed to prevent corrosion from moisture.  General wiring harnesses are included in each unit to aid in installation and mounting.  Vehicle Specific wiring harnesses are also available for certain models to further aid in installations that require intricate integration.

We found more power and better spark in the middle and top rpm in cars like the Mitsubishi EVO 5-9, 3000GT, Subaru Impreza STi, WRX, Forrester Turbo, Toyota Celica, MR2, Supra and Supra Turbo, etc. Can basically used on any car.
