Genuine BMW Crankcase Ventilation Hose

The Genuine BMW Crankcase Ventilation Hose is an original equipment engine breather hose. It is also called a crankcase breather hose or PCV hose. It carries crankcase vapors and blow-by gases from the engine block and valve cover back into the intake system, where they are burned. This helps the engine's emissions and pressure-control system work as designed.

Key Features:

• Made to BMW original equipment specifications for fit, function, and durability
• Built to handle engine heat, oil vapor, and fuel vapor exposure
• Helps regulate crankcase pressure and supports the engine's emissions control system
• Helps reduce oil leaks, rough idle, and sludge buildup caused by a worn or cracked hose
• Direct-fit OEM replacement that needs no modification

Replacing an aged or cracked crankcase ventilation hose with a Genuine BMW part helps keep the ventilation system sealed and working properly. It is a good choice for routine maintenance and repairs.
