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.
- Eliminates misfire
- Increased throttle response
- Stabilizes and smoothens idle
- Quicker starts
- 46% increase in ignition power
- Easy plug and play installation
IP Quad-Spark, sparks 2x more than the original IP Multi-Spark.
In that 1/1000 second, the Quad-Spark can fire 4 strong sparks.
