Rein ABV0205 Crankcase Breather Hose

The Rein ABV0205 is an OE-quality engine crankcase breather hose designed as a direct replacement for BMW vehicles. This vent hose is an important component of the PCV system, allowing oil vapor to travel from the crankcase to the cylinder head where it can be burned by the engine. It connects the valve cover to the intake manifold, replacing BMW OEM part number 11157553949.

Key Features:

• Constructed from durable plastic material
• Designed as a direct replacement, identical to the specs and form of the original
• Direct replacement for OE hoses with identical size, shape, and thermoplastic quick connect fittings
• Replaces OEM part number 11157553949

Over time, PCV system hoses can become clogged from blow-by and oil sludge, and individual hoses can become brittle and begin to leak. Replacing worn breather hoses helps maintain proper engine ventilation, reduces emissions, and prevents oil leaks. Rein Automotive was founded in 2007 and all products are backed by ISO 9001:2015 quality management system certification.
