Installation Notes

Verify the OE number and hose routing before installation, especially on BMW 328i, 528i, and X3 applications where intake manifold connection details can vary by engine configuration. Inspect adjoining ventilation components, seals, and connectors for wear so the replacement hose seats correctly and maintains a secure angle-connector fit.
