How to Install an Air Max Filter in a C230
The Mercedes Benz C230, like all combustion engine vehicles, must draw air into the combustion chamber in order to operate. Dust, dirt and other particulates are drawn in along with this air, and the only thing keeping them out of the combustion chamber is the air filter. An Air Max maximum-flow filter tends to do a good job of trapping these particles without choking air flow to the engine, ideally resulting in better fuel mileage.

Locate the air filter box. On the C230, the air filter box is just to the left of the engine, and it is contoured so that the right side of the box hugs the left side of the engine. You can also identify it by the thick, ridged plastic tube that runs from the front of the air filter box to the intake manifold.
