2003 Mercedes-Benz C230 Intake Manifold Parts Q&A

• Q: How do the design and replacement procedures for the variable intake manifold on 2003 Mercedes-Benz C230?

  A: In 2001-2005 V6 models, the PCM-controlled variable intake manifold optimizes the torque by switching intake runner lengths. With low speeds, the flaps push the air through shorter runners; with higher loads, longer runners facilitate charging. Subsequent models are refined to have improved combustion. Replacement entails disconnection of parts by removing the engine cover on the front.
