Fitment & Technical Details
Inspect rubber hoses, vacuum lines, and internal reed membranes for cracking, carbon fouling, or exhaust blow-by prior to replacement. Ensure proper hose routing and secure clamp tension to prevent vacuum leaks or unmetered air interference with the carburetion/fuel-injection system.Verification: Valve operates with correct one-way directional airflow check functionality, preventing hot exhaust gas reversion into the secondary air filter housing while maintaining strict compliance with factory emissions standards.
