Product Details

The Genuine BMW 11-15-1-278-804 is a crankcase ventilation hose designed specifically for BMW M20 engines. This OEM vent hose is a critical component of the engine's crankcase ventilation system, connecting the crankcase to the intake manifold to manage oil vapor and maintain proper engine breathing.

Key Features:

  • Genuine BMW OEM part ensuring exact fit and durability
  • Designed for BMW M20 2.7L engines in E30 and E28 chassis
  • Engineered with correct length, diameter, and bend angles for direct plug-and-play installation
  • Supersedes part number 11151276903
  • Restores proper intake sealing and stable idle performance

Over time, crankcase ventilation hoses become brittle, crack, and develop vacuum leaks that can impact engine performance, idle quality, and even brake booster operation. This genuine BMW replacement hose restores the ventilation system to factory specifications, ensuring optimal engine breathing and performance. Position #3 in BMW factory diagrams.
