Description

Developed over two years of rigorous testing, this kit ensures no corners were cut in its development. Installation of this kit requires either a Hondata FlashPro or another form of tunable ECU to properly manage the increased fuel flow and optimize engine performance. Without this tuning capability, the system will not function correctly. This upgrade is compatible with the Honda Civic Type R FK8 (2017-2021) and FL5 (2022+) models, providing a direct path to achieving 450HP or more.
