This air filter element, designated a fuse-type filter, protects the engine by trapping airborne particulate before it enters the intake system. It is installed in the engine air intake housing, positioned upstream of the mass airflow sensor and turbocharger inlet. A clogged or saturated element restricts airflow, causing a drop in engine power and increased fuel consumption. The manufacturer’s construction matches the housing’s seal profile, ensuring the filter seats correctly to prevent unfiltered air from bypassing the media. On reinstallation, verify the housing seals are clean and free of debris to maintain a proper seal.
