Installation Notes and Tips

Verify the hose routing, end style, and inside diameter before installation. This part uses molded connections and OE-style attachment points, so the existing mating surfaces should be clean and free of debris before the hose is seated. Confirm the left-side valve cover to intake tube application on the vehicle before ordering, especially on BMW X5, BMW 550i, and BMW 750Li models. The part number EMH250 should be matched to the original hose layout and connector style for proper fitment.
