It serves as an air intake filter that traps 99.98% of dust and soot to keep the engine clean and maintain fuel efficiency.
Compare your current filter's dimensions and check your vehicle's manual against the OEM references provided: GMC 9974319 or Porsche 91110018501.
No, this is a paper-based filter insert; washing it will degrade the synthetic resin and compromise its filtering ability.
This filter is designed for standard OEM air housings; performance with custom aftermarket cold air intakes may vary.
The glue beads maintain consistent spacing between filter pleats, preventing collapse under high airflow and ensuring maximum surface area usage.
If the filter is water-soaked, replace it immediately, as moisture can reduce airflow and lead to potential engine intake issues.
Ensure the filter is seated correctly in the housing and the housing cover is airtight; air leaks can cause sensor errors.
Check that the filter dimensions (402mm x 181mm x 41mm) match your original unit and ensure no debris is blocking the seal.
To install the Mahle LX261, locate the air filter housing in your engine bay, unfasten the clips, and remove the old unit. Clean any loose debris from the housing before inserting the new filter to ensure a perfect seal. Always verify your specific vehicle using the OEM references: GMC 9974319 or Porsche 91110018501, 91111018501, and 91111018502. This filter is also compatible with cross-references like ACDelco PC280, FRAM AF396/CA3134/CA3544, and WIX 46115. For care, inspect the filter during scheduled oil changes and replace it immediately if the media shows signs of heavy saturation or structural damage.
