2011 Lincoln Mkx Air Filter in Westborough, MA

It’s in the engine bay, inside a sealed airbox near the front corner of the 3.7L V6 intake tract.

Access typically involves unclipping or unscrewing the airbox lid and lifting the old filter out. If you prefer a professional check in Westborough, MA, our team can inspect the intake housing and MAF sealing during the same visit.

The cabin filter lives behind the glove box and targets dust, pollen, and odors for cleaner in-cabin air. Both filters are distinct parts and serve different systems.
