The Okada Projects' Plasma Direct is a direct coil replacement specially designed and developed to work as a secondary ignition amplifier increasing spark amperage 100%. Plasma Direct Coils produce 4 times more spark energy than stock coils, creating a faster flame front and quicker light-off of the fuel mixture kernel to complete combustion. With Okada Projects Plasma Direct installed on your 02-07 WRX/STI, you can feel increased torque in low RPM and get more horsepower in higher RPMs. Installing Plasma Directs is an easy direct bolt-in to the engine, no splicing or cutting into stock wiring.
