Installation Notes and Tips

Verify the OE reference and the vehicle’s climate application before ordering, since most listed fitments are marked not for cold climates. Confirm the engine and model year match the fitment table exactly, especially on BMW 330i, BMW 325Ci, and BMW X3 applications. Inspect related crankcase ventilation hoses and seals during service so the replacement can be installed on a clean, leak-free system.
