Product Details

Installation Notes and Tips

Verify the lower hose routing and connector style before installation on your BMW 528i, 525i, or 530i. Because this hose is application-specific, it installs without cutting or reshaping when matched to the correct vehicle and position. Inspect mating surfaces, quick connectors, and sealing rings before assembly to help ensure a proper seal.
