2012 Acura TL Air Filter in Marietta, GA | Nalley Acura

The engine air filter on the 2012 Acura TL is located inside the airbox in the engine bay, accessible by removing the airbox cover.

On the 2012 Acura TL with the 3.5L V6 (engine code 6VNAG3.5), the airbox sits in the engine bay and contains the replaceable media element. Access usually requires removing a few clips or screws and lifting off the airbox cover; no major trim removal is needed.

• Engine: 3.5L V6 (engine code 6VNAG3.5) — air intake feeds through the airbox.
• Typical access: unclip or remove fasteners on the airbox cover.
• Inspect housing and intake duct for debris when replacing the filter.

The cabin air filter in the 2012 Acura TL is located behind the glove box inside the passenger compartment.

Accessing the cabin filter typically requires lowering or removing the glove box and removing a cover to slide the filter out. Cabin filters protect the HVAC system and passenger breathing zone from pollen, dust, and road debris.

• Location: behind glove box on the passenger side.
• Common steps: empty glove box, release stops, remove filter cover panel.
• Inspect the housing for mold, leaves, and excessive dust when replacing.

The engine air filter cleans combustion intake air for the 3.5L V6, while the cabin air filter cleans air entering the passenger compartment and HVAC system.

The engine filter protects the engine and fuel-efficiency by preventing dirt from entering the intake; the cabin filter improves passenger air quality and HVAC efficiency. They are separate parts, housed in the engine bay (engine filter) and behind the glove box (cabin filter).

• Engine filter: protects the intake and MAF sensor; affects power and economy.
• Cabin filter: blocks pollen, dust, and particulates from the HVAC system.
• Both should be inspected during routine maintenance to maintain performance and air quality.

Common signs include reduced engine power and lower fuel economy for a clogged engine filter, and weak HVAC airflow or musty odors for a clogged cabin filter.

On a 2012 Acura TL (3.5L V6), an engine air restriction can cause hesitation under acceleration and reduced throttle response; a dirty cabin filter limits fan output and can create unpleasant odors inside the cabin. Addressing either promptly prevents secondary issues like MAF contamination or HVAC strain.

• Engine symptoms: reduced power, hesitation, or decreased MPG for the 3.5L V6.
• Cabin symptoms: weak airflow, increased dust in vents, or musty smells.
• Inspect filters during routine service or when symptoms appear.

You can often replace the engine air filter yourself with basic hand tools; the cabin filter is also replaceable but may require glove-box removal and care.

DIY replacement is common for owners comfortable with simple maintenance on the 2012 Acura TL. Nalley Acura technicians perform the same service using Acura-approved parts and will also inspect the intake housing and MAF sensor—services DIYers sometimes miss.

• Engine filter: usually accessible in the airbox and DIY-friendly.
