BMW M50 / S50 Aluminum Air Hose Connector with O-Ring – Intake System Upgrade for E36 320i, 325i, 325is, M3 & E34 Models | Replaces Part No. 11611738629

Upgrade a common factory intake connection point with a stronger, longer-lasting solution using this Aluminum Air Hose Connector with O-Ring for BMW M50 and S50 applications. Designed to replace the original plastic connector, this upgraded intake fitting provides a more durable connection point for the air hose while helping restore a tighter and more dependable seal in the intake system.

On aging BMW engines, the original plastic intake connectors can become brittle over time from repeated heat cycles, engine bay temperature, and long-term exposure to oil vapor. Once that happens, they can crack, warp, or fail at the sealing surface, which may lead to intake leaks, poor fitment, unstable idle, and reduced overall intake system reliability. Replacing that weak factory piece with a machined aluminum version is a smart upgrade for both repair and preventative maintenance.

This connector is manufactured from aluminum for improved strength and durability compared to the original plastic-style part. It also includes an O-ring to help provide a proper seal at installation, supporting smoother intake system operation and helping reduce the risk of air leaks at a critical connection point.

Whether you are refreshing an aging intake setup, replacing a failed factory connector, or upgrading to a more robust solution while servicing the engine bay, this aluminum air hose connector is a simple but worthwhile improvement for long-term reliability.

Key Features:

• Aluminum Upgrade Construction: Stronger and more durable than the original plastic connector for improved long-term reliability.
