Exhaust Camshaft for BMW E71, E82, E90, E92, E93 (N55/S55 Engines) (11317576161)

1. Part Number
   This exhaust camshaft is identified by the OEM part number 11317576161. This number is a mark of its authenticity, ensuring that it meets BMW's strict engineering and manufacturing standards. It guarantees a perfect factory - spec fit for the engines it's designed for, enabling seamless integration into the vehicle's valvetrain system.
2. Vehicle & Engine Compatibility
   It is specifically engineered for BMW models with chassis codes E71 (X6), E82 (1 Series), E90 (3 Series Sedan), E92 (3 Series Coupe), and E93 (3 Series Convertible). For engines, it's compatible with the high - performance N55 3.0L inline - 6 turbo (2009 - 2016) and S55 3.0L twin - turbo inline - 6 (used in M models from 2014 - 2020). However, it's crucial to verify your vehicle's production year and engine code to ensure exact fitment.
3. Function & Quality
   The exhaust camshaft plays a vital role in the engine's operation. It precisely controls the opening and closing of the exhaust valves, regulating the flow of exhaust gases out of the combustion chambers. This is essential for optimizing combustion efficiency, which in turn affects the engine's power output, fuel economy, and emissions. Made from high - grade heat - treated forged steel, it can endure the high temperatures (up to 220°C) and intense pressures generated within the engine. Its precision - ground lobes ensure smooth and consistent valve actuation, minimizing wear on other valvetrain components like lifters and rocker arms. Replacing a worn - out exhaust camshaft with this part restores proper valve timing, preventing power loss and extending the engine's lifespan, thus maintaining the high - performance driving experience that BMW is known for.
