Installing a HKS Blow Off Valve (BOV) can significantly enhance your vehicle’s performance by allowing it to achieve higher boost levels safely. This guide will walk you through the steps necessary to install a HKS BOV and ensure that you can achieve 15+ PSI boost without compromising engine integrity.
Tools and Materials Needed
- HKS Blow Off Valve Kit
- Socket set
- Wrenches
- Screwdrivers
- Vacuum hose
- Boost gauge (optional)
- Silicone hose clamps
- Safety glasses
- Shop towels
Step 1: Prepare Your Vehicle
Before beginning the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Disconnect the negative battery terminal to prevent any electrical issues during the process.
Step 2: Remove the Factory BOV
Locate the factory BOV, which is typically mounted on the intake manifold or near the throttle body. Use your socket set and wrenches to carefully remove the bolts securing the factory BOV in place.
Once the bolts are removed, disconnect any hoses attached to the factory BOV. Make sure to keep all hardware in a safe place for reinstallation if necessary.
Step 3: Install the HKS BOV
Take the HKS BOV and position it in the same location where the factory BOV was mounted. Align the bolt holes and secure the BOV using the provided hardware. Make sure it is tightened to the manufacturer’s specifications.
Connecting the Vacuum Hose
Connect the vacuum hose to the HKS BOV. This hose is crucial as it controls the valve’s operation based on boost pressure. Ensure the connection is secure and free from leaks.
Step 4: Adjusting the BOV for Desired Boost
To achieve 15+ PSI boost, you may need to adjust the spring tension on the HKS BOV. Refer to the manufacturer’s instructions for guidance on how to properly adjust the tension. This adjustment will help the valve open at the desired boost level.
Step 5: Reconnect the Battery and Start the Engine
Once the HKS BOV is installed and adjusted, reconnect the negative battery terminal. Start the engine and let it idle for a few minutes. This will allow you to check for any leaks or issues with the installation.
Step 6: Test Drive and Monitor Boost Levels
Take your vehicle for a test drive to evaluate the performance of the newly installed HKS BOV. Monitor the boost levels using a boost gauge if available. Ensure that you are achieving the desired 15+ PSI without any issues.
Step 7: Final Checks
After your test drive, perform a final inspection of the installation. Check all connections, bolts, and hoses to ensure everything is secure. This step is crucial for preventing any potential problems down the line.
Conclusion
Installing a HKS BOV can be a straightforward process if you follow these steps carefully. By ensuring proper installation and adjustment, you can achieve safe and effective boost levels over 15 PSI, enhancing your vehicle’s performance significantly.
