HKS Fuel Cut Defender FCD Mazda | Subaru | Toyota 1983-1995 - 4501-RA002

HKS FCD for Mazda RX-7 FD3S (1993-1995)

The HKS FCD is a must-have for Mazda RX-7 FD3S enthusiasts looking to push their turbocharged engine's performance to the next level. This electronic device is specifically designed to raise the factory fuel cut level, allowing you to safely increase boost without triggering unwanted fuel cut-offs or engine diagnostic warnings.

When you modify your RX-7 for enhanced power, the factory fuel cut can become a nuisance, causing hesitation and bogging during acceleration. The HKS FCD sends an electronic signal that adjusts the fuel cut level, preventing these issues and ensuring a smoother driving experience.

Key Features:

  • Increases Factory Fuel Cut Limit
  • Optimizes Engine Performance for Modified Boost Levels
  • Seamless Integration with F-CON V Pro or Factory ECU

Fitment:

  • Mazda RX-7 FD3S (1993-1995)

Customer Feedback:

Users have reported significant improvements in throttle response and overall driving dynamics after installing the HKS FCD. By preventing fuel cut issues, drivers enjoy a more reliable power delivery, especially during high-boost scenarios.

Important Note:

  • Installation of the FCD may allow for higher than recommended boost levels, which can lead to engine damage. It is recommended to upgrade your fuel delivery system and consult a qualified technician prior to installation.
