Okada Projects Okada Projects Plasma Spark Kit WRX 2006-2014 / STI 2004-2019 / Legacy GT 2005-2009 / Forester XT 2004-2013
The Okada Projects' Plasma Spark is a spark plug boot (socket) specially designed and developed to work as a secondary ignition amplifier. An Okada Projects Plasma Spark for the WRX/STI creates stronger sparks in a very short time (nano-seconds), creating a faster flame front and quicker light-off of the fuel mixture kernel to complete combustion. With Okada Projects Plasma Spark installed on your WRX, you can feel increased torque in low RPM and get more horsepower in higher RPMs. Installing Plasma Sparks is an easy direct bolt-in to the engine, no splicing or cutting into stock wiring: Simply replace the OEM Subaru spark plug books with the Okada Projects Plasma Spark units. Sold as a set of four (4).
