Key Features & Benefits – EPMAN recirculating adjustable blow off valve red
The EPMAN recirculating adjustable blow off valve red is a recirculating BOV where the vented air volume is adjustable, and the adjustment can be made independently from the relief pressure. It is also listed for Subaru WRX 2.0L Turbo (2015–2017) applications.
The body is made from 6061 aluminum and the spring is stainless steel. A visible Soft/Hard scale helps you repeat settings when tuning drivability around lift-off and gear changes.
When is this useful?
It is useful on turbo systems during throttle lift and shifts to relieve charge-side pressure, while recirculation supports controlled airflow in layouts where routing and MAF placement benefit from keeping the air in the system.

Selection & installation tips
- System match: confirm the housing layout and bolt-on flange pattern match your intercooler/charge-pipe mounting point.
- Recirc route: verify where the recirculation return connects and ensure the hose run is not kinked or preloaded.
- Vacuum/boost reference: connect the control line to the correct reference source and match 1/4" or 1/2" to your hose setup.
- Adjustment: make small changes along the Soft/Hard scale, then evaluate behavior during shifts before locking in the setting.
- Leak check: re-check clamps, flange sealing, and all joints after installation to prevent boost leaks.
Before installation, compare your flange layout, hose connections, and recirculation return location to the specs above, then tune the setting gradually with controlled test pulls.
