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

The engine air filter on the 2011 Acura RL is located inside the engine bay airbox at the front passenger-side intake area.

On the 2011 Acura RL you access the engine air filter by opening the hood and removing the clamps or screws on the plastic airbox cover; the filter sits inside the housing that feeds the intake tract. Because the 2011 Acura RL uses a 3.7L V6 intake, the airbox is designed for straightforward access but may require a simple tool to release clips.

• Located in the engine bay airbox on the passenger-side intake.
• Remove cover clips or screws to reach the filter element.
• Inspect the intake housing and MAF sensor while the airbox is open.

The cabin air filter on the 2011 Acura RL is located behind the glove box inside the passenger compartment.

Accessing the cabin filter typically requires lowering or removing the glove box to reach the filter housing cover; on the 2011 Acura RL this placement helps filter HVAC air for occupants but can collect pollen and road dust quickly in Georgia climates. A visual inspection reveals if the cabin filter needs replacement or if debris is blocking airflow.

• Found behind the glove box in the passenger compartment.
• Glove box removal or lowering grants access to the filter housing.
• Check for pollen, leaves, or dark soot when inspecting.

The engine air filter cleans intake air for combustion, while the cabin air filter cleans air entering the HVAC system for passengers.

For the 2011 Acura RL the engine filter protects the 3.7L V6 from dust and debris that reduce power or damage the engine; the cabin filter protects occupants from pollen, dust, and road dust that reduce HVAC airflow and cause odors. Each filter serves a distinct function and is sized and rated differently for its task.

• Engine filter protects the intake system and engine components.
• Cabin filter protects HVAC components and passenger breathing air.
• Both should be inspected regularly for optimal performance.

These symptoms are common in Georgia after high-pollen seasons or dusty road conditions.

• Engine: reduced power, loss of mpg, rough idle.
• Cabin: weak airflow, odors, increased dust in cabin vents.
• Visual inspection often confirms heavy dirt, leaves, or soot.
