Description

The HIGHSPARK IGNITIONCOIL Japan Ignition Coil Upgrade Kit is engineered to transform the driving experience for Infiniti G37 Convertible 3.7L models from 2009 to 2013. This kit delivers significantly improved engine responsiveness, horsepower, and overall efficiency. It features a spark output that is 2 to 2.5 times more powerful than OEM ignition coils, leading to enhanced throttle response, increased horsepower, and better low-speed torque. The ignition coils also stabilize constant voltage output for smoother engine operation and reduced jerking. Constructed with premium German copper wire and Japanese Kyocera resin, these ignition coils offer increased heat resistance and resilience, making them suitable for high-performance applications. They continuously generate a high-energy spark, with a peak voltage of 15 kV compared to the OEM's approximate 10 kV, ensuring extended performance. The upgrade helps improve combustion efficiency for a more exhilarating and reliable driving experience.
