How to Install WG9725190901 Air Inlet Pipe – Step-by-Step Guide
Safety First: Turn off the engine and disconnect the battery before starting work.
Remove Old Pipe: Loosen the hose clamps at both ends (air filter outlet and turbocharger inlet) using a wrench or screwdriver. Carefully detach the old inlet pipe.
Inspect Components: Check the condition of clamps, connectors, and sealing surfaces. Replace if damaged or corroded.
Fit New WG9725190901 Pipe: Align the new air inlet pipe between the air filter assembly and the turbocharger inlet. Ensure proper seating without twisting.
Secure Clamps: Reinstall or replace hose clamps and tighten evenly to prevent leaks (do not over-tighten).
Test System: Start the engine and listen for whistling or hissing sounds indicating air leaks. Inspect during idle and acceleration.
Final Check: Confirm all connections are secure and there is no contact with moving parts or hot surfaces.
