BMW 325i Air Filter

The BMW 325i Air Filter ensures the engine stays clean, helps trap dirt before it reaches the intake, and prevents loss of power and mileage. The BMW engine requires up to 10,000 gallons of air per gallon of fuel. When the Air Filter clogs, it starves airflow, which saps acceleration and economy. So, replace this every year. The early 325i editions featured a round Air Filter with a lid that sat on top of the carburetor. The later fuel-injected 325i versions utilize a flat-panel Air Filter located in a side-mounted air box. You can access the panel-type filter by unclipping a few clips. The two types of shapes use pleated paper Air Filter media that can capture particles as small as five microns while offering ample flow. This dry paper design has a high dirt capacity and low cost compared to the oiled cotton style in racing setups, so it is standard on BMW cars. Timely replacements allow the BMW 325i to run more smoothly. They protect the cylinders, sensors, and plugs from abrasives. This allows the computer to hold an ideal air-fuel ratio.
