Installation Notes and Tips

Verify the OE number on the original part before ordering, especially on Audi A4, Audi TT, Volkswagen Beetle, Volkswagen Passat, Volkswagen Jetta, and Volkswagen Golf applications. Compare the existing connector shape and hose routing points to the listed dimensions: 65 mm height, 49 mm length, and 35 mm width. Inspect adjoining breather hoses for brittleness, oil saturation, or cracking before installation so the repaired ventilation path seals correctly.
