Improves combustion efficiency!
Increases horsepower at all RPM!
Improves torque at low and middle RPM and stabilizes voltage!
Excellent starting performance and stable idling!
Very simple installation for both Plug Wire and Direct Coil!
For Plug Wire
High voltage current boosted by coil flows through Plug Wires, and reverse induced current takes place. Such reverse current prevent smooth flow of required current and decreases the original performance of Plug. This unit produces a stronger spark. It is applicable to original plug wire and also most of normal plug wires.

For Direct Coil
Small current is charged on the iron core of Direct Coil, and also slight leakage occurs. Consequently, the direct coils are not performing as it is originally designed. Installation of D-Spark eliminates charging of current and leakage at the iron core.It stabilizes the difference of potential among each coil and maximizes the original performance. Then it brings stronger spark.
