URO 11151719841 Engine Crankcase Breather Hose

Engine Crankcase Breather Hose for BMW

This URO engine crankcase breather hose restores crankcase ventilation function on select BMW applications. Built from EPDM and formed with molded branches, it is made for direct replacement use on vehicles such as the BMW 535i and BMW 735i with electronic engine performance control.

Key Features

• EPDM construction resists cracking and splitting from engine heat and oil vapor
• Molded hose design for a direct OE-style routing profile
• Two branches and three hose connectors for the specified crankcase ventilation layout
• Replacement for BMW part number 11151719841
• Fits 1987-1993 BMW 535i, 735i, and 735iL applications listed below

Product Details

This crankcase breather hose is part of the emission control and crankcase ventilation system. On the BMW 535i, BMW 735i, and BMW 735iL, the hose helps route crankcase vapors through the proper ventilation path so the system can maintain hydrocarbon control and stable breather operation. The molded EPDM construction supports consistent fitment and durability in a high-heat, oil-exposed engine bay. Part number 11151719841 is a direct reference for the listed OE application.

This part cross-references Genuine 11151719841 and URO-000450 for the same application.

Vehicle Fitment

• Fits 1989-1993 BMW 535i, N/A, w/ Electronic engine performance control
• Fits 1987-1992 BMW 735i, N/A, w/ Electronic engine performance control
• Fits 1988-1992 BMW 735iL, N/A, w/ EML (engine management light)

What It Helps Resolve

• Cracked or split crankcase breather hose
• Oil vapor leakage at the ventilation hose
• Improper crankcase ventilation routing
• Hydrocarbon emission control issues related to a failed hose
• Vacuum or breather system performance problems caused by hose deterioration

Installation Notes

Verify the vehicle’s engine management configuration before ordering, especially on BMW 535i, BMW 735i, and BMW 735iL models with electronic engine performance control or EML. Compare the original hose routing, branch count, and connector count to the replacement part before installation. Inspect adjoining breather components for heat damage, oil saturation, or cracking so the new hose can seal and route correctly.

Quality Assurance

URO backs this hose with a 24-month unlimited mileage warranty. The replacement is built from heat- and oil-vapor-resistant materials and is intended to restore proper crankcase breather function on the specified BMW applications.
