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

The engine air filter on the 2011 Acura TSX is located in the engine bay inside the sealed airbox (the intake housing).

The airbox is accessible from the engine compartment and is designed to channel outside air through the replaceable paper filter element before it reaches the throttle body. Nalley Acura technicians in Marietta inspect the airbox seals and fasteners as part of the replacement to prevent unfiltered intake air.

• Found in the engine bay inside the sealed airbox.
• Access usually requires releasing clips or a few fasteners.
• Technician checks housing seals and intake ducting for leaks.

The cabin air filter on the 2011 Acura TSX is located behind the glovebox.

Removing the glovebox or its limiting stops provides access to the HVAC intake door and the cabin filter slot. Nalley Acura inspects the HVAC intake, checks for debris, and replaces the cabin filter to restore airflow and reduce pollen, dust, and odors inside the vehicle cabin.

• Accessed from behind or under the glovebox assembly.
• Replacement restores HVAC airflow and reduces allergens.
• Technician checks HVAC intake for leaves or rodent debris.

The engine air filter protects the engine by cleaning combustion air; the cabin air filter protects passengers by filtering HVAC air.

The engine air filter prevents dust and debris from entering the intake and affecting combustion, throttle response, and fuel economy. The cabin filter traps pollen, dust, and exhaust particulates before they enter the passenger compartment through the HVAC system. Both serve different systems and should be inspected separately during maintenance.

• Engine filter = protects combustion system and sensors.
• Cabin filter = improves in-cabin air quality and HVAC flow.
• Technicians inspect both for optimal vehicle performance and comfort.

Common signs on a 2011 Acura TSX include reduced engine power, lower fuel economy, rough idle, and weak HVAC airflow or musty cabin odor.

If the engine air filter is clogged, you may notice sluggish acceleration or decreased highway mpg. If the cabin filter is clogged, HVAC vents will have reduced flow and may emit odors or allow more dust into the cabin. Nalley Acura technicians perform a visual inspection to confirm the condition and recommend replacement.

• Engine symptoms: reduced power, rough idle, and decreased fuel economy.
• Cabin symptoms: weak HVAC airflow, dust in vents, or musty smell.
• Inspection identifies whether filter or related components need service.

You can often replace the engine air filter yourself on a 2011 Acura TSX, but Nalley Acura is recommended for cabin filters and inspection of intake components and sensors.

The engine filter is typically accessible and DIY-friendly for drivers who have basic tools; the cabin filter requires glovebox removal and can involve clips and trim. Nalley Acura adds value by using Acura-approved filters, inspecting the intake housing and MAF area, and documenting condition for warranty or maintenance records.

• Engine filter: usually a simple swap with basic tools.
• Cabin filter: may require glovebox trim removal and care.
• Dealer service includes inspection of intake, MAF, and seals.
