⛽ Performance Fuel Rail Included
This setup also comes with a high-flow performance fuel rail designed to support increased fuel delivery requirements for both naturally aspirated and forced induction applications.
Included with the fuel rail:
✔ AN fittings in your preferred size and configuration
✔ Improved fuel distribution across all cylinders
✔ Compatible with high-performance fuel systems
✔ Clean and professional motorsport-style installation
💨 CNC Vacuum Distribution Block Included
Every kit includes a CNC-machined vacuum block that combines vacuum signals from all six individual throttle bodies into a single, stable vacuum source.
This is essential for ITB-equipped engines because each throttle runner produces a pulsing vacuum signal. By combining all runners, the vacuum block creates a smoother and more usable vacuum reference for:
✔ MAP sensor input for standalone ECU tuning
✔ Fuel pressure regulator reference
✔ Brake booster assistance (where applicable)
✔ Idle control systems
✔ Boost control devices
✔ Vacuum gauges and data logging equipment
The result is a cleaner vacuum signal, improved ECU accuracy, more stable engine operation, and easier tuning.
