2011 Acura TSX Air Filter in Marietta, GA | Nalley Acura

The engine air filter on the 2011 Acura TSX sits in an intake-style housing under the hood serving the 2.4L inline-4 engine.

On the 2011 Acura TSX the airbox and rectangular filter are accessible from the engine bay; you can see the intake housing once the hood is open. Nalley Acura technicians in Marietta inspect the housing for damage, proper seals, and oil or debris that could affect airflow to the 2.4L engine.

• Located in the engine bay, inside a plastic airbox.
• Serves the 2.4L inline-4 intake tract.
• Technicians check sealing surfaces and intake ducting for leaks.

The engine air filter protects the 2.4L engine's combustion airflow while the cabin filter protects passenger air flowing through the HVAC system.

For the 2011 Acura TSX, the engine air filter ensures clean air for combustion and supports the vehicle's rated 201 horsepower, while the cabin filter removes pollen, dust, and road debris before air reaches occupants. Nalley Acura inspects both to preserve engine performance and in-cabin air quality for drivers across Marietta and surrounding neighborhoods.

• Engine filter: on the intake side, protects combustion and performance.
• Cabin filter: behind the glove box or HVAC plenum, filters passenger air.
• Both are inspected for clogging and replacement as needed.

Common signs on a 2011 Acura TSX include reduced throttle response relative to its 201 hp rating, poorer fuel economy versus the EPA figures (22 city / 31 highway), and reduced HVAC airflow or musty cabin odors.

A clogged engine filter limits airflow into the 2.4L engine causing sluggish acceleration and possible higher fuel use; a clogged cabin filter reduces blower output and can produce stale or musty smells inside the car. Nalley Acura inspects both filters and the intake/vent ducts when customers report these issues.

• Reduced acceleration or hesitation under load.
• Lowered fuel efficiency compared to 22 city / 31 highway EPA estimates.
• Weak HVAC airflow, unusual odors, or increased dust in the cabin.

Many owners can replace the engine air filter on a 2011 Acura TSX themselves, while the cabin filter often requires glove-box access and moderate trim removal.

The engine air filter in the 2011 Acura TSX is generally accessible and is a common DIY task; however, Nalley Acura offers a full inspection that includes intake sealing, MAF sensor visual checks, and proper disposal of the old filter.

The cabin air filter on a 2011 Acura TSX is located behind the glove box within the HVAC plenum area.
