HIGHSPARK IGNITIONCOIL Japan Ignition Coil Upgrade Kit for Lexus RC-F 5.0L 2015-2021 - HS-LexusRC-F-1521-8p

HIGHSPARK IGNITIONCOIL Japan Ignition Coil Upgrade Kit for Lexus RC-F 5.0L 2015-2021 - HS-LexusRC-F-1521-8p performance upgrade part

This ignition coil upgrade kit is designed for the Lexus RC-F 5.0L (2015-2021) to improve ignition performance and overall engine response. It focuses on lower latency and higher spark output to support smoother operation and more consistent combustion under demanding driving conditions.

SKU: HS-LEXUSRC-F-1521-8P

Key Benefits

• Delivers 2–2.5 times OEM spark output for stronger ignition performance.
• Improves throttle response, horsepower, and low-speed torque through better combustion efficiency.
• Stabilizes voltage output to reduce engine jerk during start and re-start.
• Uses premium German copper wire with Japanese Kyocera resin for heat resistance.
• Produces high-energy spark with 15 kV peak voltage versus OEM around 10 kV.
• Supports performance driving needs including drag racing, road racing, and drifting.
• Designed for reliability and consistent power delivery in street or track use.

Notes

• Standard kits suit street use with occasional track driving.
• Premium kits are intended for heavy track use and higher voltage at high RPMs.

Built as an ignition system performance upgrade, this kit targets smoother operation and stronger spark energy where OEM coils may fall short. The combination of stabilized voltage and increased output helps maintain consistent engine behavior across everyday driving and higher-load conditions, while the heat-resistant construction supports sustained performance.
