Overview

The HIGHSPARK IGNITIONCOIL Japan Ignition Coil Upgrade Kit is designed for the Infiniti G35 Sedan 3.5L 2007-2008. It aims to provide smoother starts and improved engine performance by enhancing reliability and fuel efficiency.

This kit features ignition coils engineered for increased spark output, which is 2-2.5 times more powerful than OEM coils. This leads to improved engine responsiveness, better throttle response, increased horsepower and low-speed torque, and greater combustion efficiency for a smoother ride. The coils also stabilize voltage output and reduce engine jerk at startup.
Show original supplier description
The HIGHSPARK IGNITIONCOIL Japan Ignition Coil Upgrade Kit is engineered for the Infiniti G35 Sedan 3.5L with the VQ35HR engine, specifically for the 2007 and 2008 model years. The core benefit of this upgrade lies in its substantial increase in spark output, delivering 2-2.5 times more power than OEM ignition coils. This heightened spark energy translates directly into tangible performance gains, including improved engine responsiveness, a more immediate throttle response, and increased horsepower and low-speed torque. Furthermore, the enhanced combustion efficiency contributes to a smoother driving experience. Constructed with premium materials, these ignition coils feature German copper wire fused with Japanese Kyocera resin, offering increased heat resistance and durability for long-lasting performance. The design focuses on stabilizing voltage output, ensuring consistent and reliable operation, and minimizing engine jerk during startup and restarts. For those pushing their vehicles to the limit, the HIGHSPARK IGNITIONCOIL kit generates a high-energy spark with a peak voltage of 15 kV (compared to OEM's ~10 kV), making it ideal for racing applications such as drag racing, road racing, and drifting.
