Notes:
  • Quad Spark Coils

More Info:
Quad spark coils create a secondary voltage and produce a 46% increase in secondary current. At RPMs below 3K, the coils fire off 4 times rather than once. This increases low end response and operation. After 3K, the coils switch back to 1 power spark which is critical for performance engines. Direct fit and does not require a new controller or igniter.

The more fuel and air that is fed into your engine, the stronger the spark must be to properly ignite the mixture. Ignition Projects' goal was to produce high quality, high performance coils for exactly this purpose. Ignition Projects coils pack a powerful punch; 10 punches to be exact! Each discharge from the coil fires a ultra-fast multi-spark discharge that carries 10 sparks all across the RPM range! This patented technology ensures that every bit of the air fuel mixture is efficiently burned through, maximizing performance. The amperage is also elevated to 100% above the stock coil, allowing each spark reach father and deliver a truly strong jolt of energy. Each kit will include the exact amount of coil packs needed and is fully plug and play.

These coils were engineered in Japan and assembled in the USA. Their high quality materials and build quality ensures reliable and continuous performance in street or race applications.

Key Features:
  • Much stronger than the weak factory coil packs (100% more amperage than stock).
  • Ensures that all of the voltage from your ignition system actually reaches the spark plugs.
  • Uses patented technology to generate ultra-fast multi-spark discharges of 10 sparks across the RPM range!
  • Results in increased engine power and efficiency.
  • Replaces all factory coils in your Subaru WRX STI.
  • EASY installation - these coils are direct plug-in replacements. No modification required.
  • Backed by a 1 year limited warranty.
