Detailed Description

Wix 42106 is an engine air filter designed around the dimensions and airflow needs of select Mercedes-Benz diesel engines. With a 3.375-inch height, 12.000-inch top and bottom outer diameter, and 8.800-inch inner diameter bottom, it uses cellulose media and plastic ends to support consistent filtration performance.
