Ignition Projects Quad Spark Ignition Coil Packs
2004-2010 Subaru WRX / STI
Features & Product Details
RallySport Direct proudly carries quality ignition upgrades and accessories brought to you by Ignition Projects.
These are the Ignition Projects Quad Spark Ignition Coil Packs. These coil packs have been designed using Ignition Project's Quad-Spark technology which creates a secondary voltage that produces a 46% increase in secondary current. Powerful quad sparks are generated in 1/1000 of a second at low-mid RPM (up to 3000 RPM) increasing throttle response and low-end drivability. After 3000 RPM, the coil switches to a powerful single spark which is critical for performance engines.
