⚙️ WHAT THIS PART DOES - CRITICAL ENGINE COMPONENT

This small but vital O-ring gasket is a crucial component in your Subaru's turbocharged engine system. It serves as the primary seal for the turbocharger bypass valve (BPV), also known as the blow-off valve.

🔒 Pressure Seal

Creates an airtight seal between the bypass valve and intercooler system

🎯 Boost Control

Maintains proper boost pressure regulation during throttle transitions

🛡️ System Protection

Prevents boost leaks and protects turbocharger from damage

⚠️ WHY YOU NEED THIS PART - SYMPTOMS OF FAILURE

🔍 Common Warning Signs:

Audible boost leaks (hissing sounds)

Loss of turbo boost pressure

Poor throttle response

Check engine light activation

Increased fuel consumption

Turbo flutter or surge

💥 Consequences of Ignoring:

Reduced engine power and torque

Poor fuel economy

Potential turbocharger damage

Engine management complications

Failed emissions testing

🔄 HOW THE TURBOCHARGER BYPASS VALVE SYSTEM WORKS

1

Boost Building

Turbocharger compresses air through intercooler to engine

2

Throttle Closure

Throttle body closes, creating high-pressure wall

3

Pressure Relief

Bypass valve opens to relieve pressure

4

Air Recirculation

Pressurized air redirected back to intake system

🎯 The O-ring (Part #22656AA020) seals the connection between the bypass valve and intercooler piping, ensuring no boost pressure escapes during this critical process.

📍 SYSTEM LOCATION & INSTALLATION

Component Connections:

Intercooler outlet piping (high-pressure side)

Bypass valve assembly (mounted on intercooler or piping)

Recirculation line (returns to turbo inlet)

🔧 Installation Recommendations:

Professional installation recommended for optimal results

Replace during bypass valve service or when boost leaks detected

Use genuine Subaru assembly lube for proper installation

Follow torque specifications to prevent damage
