The HIGHSPARK IGNITIONCOIL Japan Ignition Coil Upgrade Kit is a performance enhancement designed for the Infiniti G37 Convertible 3.7L, covering model years 2009 through 2013. It provides a spark output that is 2-2.5 times more powerful than OEM ignition coils, which can lead to a significant boost in engine performance. Constructed with premium German copper wire fused with Japanese Kyocera resin, these ignition coils offer increased heat resistance and resilience, making them suitable for high-performance applications. They generate a high-energy spark continuously, with a peak voltage of 15 kV, surpassing the OEM's approximate 10 kV, providing extended performance benefits. This kit also stabilizes voltage output for smoother engine operation and reduced jerkiness during start and restart phases. The HIGHSPARK IGNITIONCOIL kit is versatile, suitable for street applications with occasional track usage, and also offers premium kits tailored for heavy track usage. This upgrade is intended to transform the driving experience, making it more exhilarating and enjoyable.
