HKS Blow Off Valve
Universal Fitment for Most Models
71008-AK004
Overview:
The HKS Blow Off Valve (BOV) is a high-performance component designed to improve the boost control and response of turbocharged engines across a wide range of vehicles. Featuring a universal fitment, this valve is ideal for enthusiasts who demand reliable and consistent operation regardless of boost pressure levels. Whether you drive a daily commuter or a high-powered performance machine, the HKS BOV helps maintain optimal boost pressure while delivering the distinctive sound and quick throttle response that turbocharged engines are known for.
Engineered with HKS’s original 3-chamber structure, this blow off valve ensures stable operation under varying boost conditions. Its large 51mm valve size is especially suited for high-power and large displacement engines, providing excellent airflow and durability. The adjustable preload setting allows you to fine-tune the air release timing to match your specific setup, making it a versatile choice for many turbocharged applications.
Key Features:
The HKS Blow Off Valve combines advanced design and durable construction to deliver reliable performance and enhanced driving experience. Key features include:
- Large 51mm valve diameter optimized for high power and large displacement turbocharged engines.
- Original 3-chamber design that stabilizes valve operation regardless of boost pressure variations.
- Reliefless type mechanism that eliminates the need for spring load adjustments, ensuring consistent valve response at all boost levels.
- Adjustable preload setting to customize air release timing for a wide range of vehicle and boost configurations.
- Durability tested for over 1 million operations to minimize valve sticking and maximize long-term reliability.
- Includes an installation flange for secure mounting; flange requires welding to a pipe for proper installation.
Construction & Design:
The HKS Blow Off Valve is crafted with precision engineering to withstand the demands of high-performance turbocharged engines. Its robust 3-chamber structure enhances stability and prevents premature valve opening or boost leaks. The large valve diameter supports increased airflow, which is critical for maintaining boost pressure in engines with higher power outputs or larger displacement.
The reliefless design removes the traditional reliance on spring load settings, which can be difficult to optimize for different vehicles and boost levels. This innovation ensures the valve opens and closes precisely when needed, improving throttle response and maintaining boost consistency. The valve’s components are built to endure rigorous use, backed by extensive durability testing to ensure long-lasting performance.
Installation & Fitment:
This HKS Blow Off Valve is designed for universal fitment, making it compatible with most turbocharged vehicles. It requires welding the included flange to a suitable pipe, so professional installation is recommended to ensure a secure and leak-free connection. Note that a piping hose is not included with the valve and must be sourced separately.
No special tuning or spring load adjustments are necessary thanks to the reliefless design, simplifying installation and setup for a wide range of applications.
