Ignition Projects Quad Spark Ignition Coil Packs - Spark 4X for More Efficiency !

With constant research and development, we were be able to build the 
Quad-spark system directly into the ignition coil without using an external discharge box.  Our Quad-spark technology creates a secondary voltage and 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.  As with all products from Ignition Projects, Quad-spark ignition coils are direct plug and play with the stock wiring harness. No cutting or splicing involved.
