Universal Diesel Blow-Off Valve HKS SQV4 Style (TK-DBSQV4) - Optimal Performance with Intelligent Control
This HKS SQV4 style diesel blow-off valve is perfect for turbocharged diesel engines, where reducing turbo pressure backflow is essential. The kit includes all necessary components for easy installation:
- Diesel blow-off valve control module
- Solenoid for blow-off valve control
- 25mm blow-off valve
- Aluminum adapter for intercooler hose attachment
- Wiring harness between control module and solenoid
- 3mm yellow vacuum silicone hose (1m)
The solenoid requires connection to the vacuum pump and intake manifold pressure. The control module monitors the 5V signal from the electronic accelerator pedal. If the blow-off valve has a strong pre-tension spring or the engine’s vacuum pump is weak, an additional vacuum reservoir might be needed, which is available in our webshop. Should the solenoid operate without the valve opening, this could indicate insufficient vacuum strength.
The intelligent control unit monitors pedal position, activating the solenoid based on throttle release. For greater throttle inputs, it operates the solenoid for longer, ensuring smooth performance and faster response.
