Your car's intake manifold is a very important component to take care of. The intake manifold is a part of your Mercedes' engine and helps to distribute air from outside your vehicle to the different cylinders in the engine. The air is needed to combine with air to help produce power. Your manifold is attached to the cylinder head with a gasket in between that provides a tight seal. It's important to keep the manifold and the gasket both in good condition so that your engine can function properly. If the intake manifold is starting to go, something you might notice is coolant leaking on the ground. A bad intake manifold can also develop an air leak that causes your engine to roughly idle or even stall. You might also notice reduced performance coming from your engine. Be sure to check the temperature of your car to see if it's overheating, as well. When you need a new intake manifold, find an OEM one for your Mercedes-Benz here on our site.
