Engine Mount

The Genuine Mercedes-Benz intake manifold, part number 2721403001, is a direct replacement component designed to ensure proper air-fuel mixture distribution to your engine's cylinders. As a Genuine Mercedes-Benz part, it meets the high standards set by the manufacturer for quality, reliability, and durability. This manifold is manufactured in the United Kingdom. An engine intake manifold's failure can lead to symptoms such as engine misfires, rough idling, coolant or vacuum leaks, and a Check Engine Light. This component is crucial for stable combustion and overall engine performance. This intake manifold is specifically designed to fit the 2009-2011 Mercedes-Benz SLK350 models with the 3.5L V6 engine (272.969 Gas), including vehicles with Code M014. It is a direct fit replacement for the original part. According to user feedback, this intake manifold allows for more airflow and potential top-end power gains on the M272 engine. It features a single-stage, fully plastic design that omits vacuum-actuated dual-stage flaps, which can help reduce heat soak in the engine's V and allow colder, denser air into the cylinders. However, this modification requires the A2731410325 throttle body and A2731400118 intake elbow from the M273 V8 engine for full compatibility. Without a proper tune after the swap, a loss of low-end torque may be noticed due to the absence of flaps optimized for lower RPMs. The ECU will not throw a check engine light even with the associated wiring harness connectors unplugged.
