How many air filters does a Acura TLX have?
The Acura TLX has two air filters: one for the engine air intake and one for the cabin air system. This quick guide explains what each filter does, where to find them, and how often to check or replace them.
Air filters are essential for engine performance and interior comfort. Understanding their roles helps you keep the TLX running smoothly and the cabin fresh, especially in dusty or polluted environments.
Two main air filters and their roles
The TLX relies on two primary filters to protect the engine and keep interior air clean. The list below identifies each filter and its purpose.
- Engine air filter — cleans air entering the engine to optimize performance and fuel efficiency
- Cabin air filter — traps dust, pollen and other particulates from the air entering the passenger compartment
With both filters in place, the TLX can maintain efficient combustion and comfortable cabin air quality.
Where to find and access each filter
Access points differ by filter. The following brief overview helps you locate them and plan replacement without guesswork.
- Engine air filter: located in the engine bay inside the air intake housing, usually a rectangular box with clips or screws that can be opened to swap the filter
- Cabin air filter: located behind the glove box on the passenger side or under a panel on the dash/footwell area, depending on model year; replacement typically requires lowering the glove box and removing a cover to expose the filter
Regular checks help ensure the engine breathes clean air and the HVAC system remains efficient.
Maintenance considerations
While the exact replacement intervals vary by model year, Acura generally recommends inspecting both filters at regular service intervals and replacing them when they become dirty or clogged. Common guidance ranges are:
- Engine air filter: roughly every 30,000 miles or sooner in dusty conditions
- Cabin air filter: roughly every 15,000 to 25,000 miles, or once a year in typical use
Always consult the owner's manual or a dealer for the precise intervals for your TLX variant and driving environment.
Summary
In short, the Acura TLX uses two air filters: one for the engine and one for the cabin. Knowing their locations and replacement timelines helps maintain performance and comfort.
