Ignition Projects M136406Q Quad Spark Coil Pack for 2010-2019 WRX / STi / Forester / Legacy / Outback

Ignition Projects

IP-M136406Q


IP Quad-Spark coils for 2.5L H4 engine vehicles

FEATURES: 

  • Eliminates misfire
  • Increased throttle response
  • Stabilizes and smoothens idle
  • Quicker starts
  • 46% increase in ignition power
  • Easy plug and play installation

With constant research and development, Ignition Projects were able to build the 
Quad-spark system directly into the ignition coil without using an external discharge box.  Ignition Projects' 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 driveability. 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.

Comparison to factory ignition coil to the IP Power Quad-Spark


 Quad-Spark, sparks 2x more than the original Multi-Spark.

In that 1/1000 second, the Quad-Spark can fire 4 strong sparks.
