URO 11617504535 Engine Crankcase Breather Hose

Engine Crankcase Breather Hose for BMW

This URO engine crankcase breather hose is a direct replacement for the failed OE hose used in the crankcase ventilation system. It restores breather function for proper hydrocarbon vapor control on select BMW applications, including BMW 325i, 330i, X5, and related models.

• Direct-fit replacement for the crankcase breather hose from the vent valve
• Made from PA6 GF30 for strength and heat resistance
• Molded hose design with 2 branches and 3 hose connectors
• Resists cracking and splitting from engine heat and oil vapor exposure
• Guaranteed fitment for listed BMW applications
• Part number: 11617504535

Product Details

Built for the emission control and crankcase ventilation system, this hose helps restore the routing of blow-by vapors from the vent valve back into the engine system. The molded construction supports consistent fitment, while the PA6 GF30 material is selected to handle the heat and oil vapor conditions common in this location. End diameters measure 0.48 in., 0.49 in., and 0.18 in., matching the hose connection points used on the listed BMW fitments. This part number, 11617504535, is also referenced by Genuine and other aftermarket cross-references for the same application.

Installation Notes

Replace the hose when the original part shows cracking, hardening, or oil-soaked deterioration. Confirm the hose routing from the vent valve before installation and verify that all connection points are fully seated. This part is listed for BMW 325i and BMW 330i applications, along with other compatible BMW models shown above, and the molded shape is intended to match the OE routing.
