Detailed Description

The Gates EMH071 emission control hose is engineered to match the original hose layout used in the crankcase ventilation system. With an 18-inch centerline length, 16 mm inside diameter sections, and a 5 mm branch section, this molded hose is shaped to follow the factory path between valve covers. It is a direct replacement for BMW part numbers 11157601451, 11157601452, 11157622488, 11157640285, 11158637873, and 11158647961, and it cross-references EMH071 for the same application. This part is used on BMW 650i, 550i, and 750i platforms where the original hose connects valve cover to valve cover.

What It Helps Fix

• Cracked or brittle crankcase breather hose sections
• Vacuum leaks caused by deteriorated emission hose material
• Improper crankcase ventilation routing
• Check engine light concerns related to emission system airflow
• Oil vapor control issues from damaged hose connections

Installation Notes

Verify the hose routing, connector style, and valve cover-to-valve cover layout before installation. This hose uses clip-on and push-in end types with molded branches, so alignment with the factory connection points is important for proper fit. Confirm the vehicle application by year, make, model, and position before replacing the original hose.
