BMW N63 Crankcase Vent Hose Pipe Set Left & Right Bank – OEM PCV System Replacement for F01, F02, F07, F10, F12, F13, E70, E71, F15 & F16 Models | Replaces Part No. 11157646086, 11157646087

Restore proper crankcase ventilation and long-term engine reliability with this OEM-style Left and Right Crankcase Vent Hose Pipe Set for BMW vehicles equipped with the N63 twin-turbo V8 engine. Designed to replace aging or damaged factory breather hoses on both banks, this complete replacement set helps regulate crankcase pressure, manage oil vapor flow, and support smooth, consistent engine operation.

The BMW N63 engine relies on an efficient crankcase ventilation system to control internal engine pressure and route oil vapors back through the intake system correctly. Over time, the factory vent hoses can become brittle, crack, collapse, or develop leaks from constant exposure to heat, oil vapor, and turbocharger-related engine bay temperatures. Once these hoses begin to fail, they can contribute to vacuum leaks, rough idle, pressure irregularities, excessive oil consumption, check engine lights, reduced fuel efficiency, and poor overall drivability.

This complete left and right bank hose set is designed to restore proper PCV system function by replacing both factory breather hose assemblies at the same time. Servicing both sides together is a smart preventative maintenance approach on the N63 platform, especially when one hose has already started to deteriorate or when the engine is showing signs of crankcase ventilation issues.

Manufactured from durable automotive-grade materials, these replacement hoses are built to withstand the demanding conditions of the N63 engine bay while providing dependable long-term performance. The precision-molded design helps ensure OEM-style fitment and secure connections across both cylinder banks, making installation straightforward with no modifications required.
