Engine air filter replacement typically costs about $70 to $120 at a shop, while cabin air filter replacement usually runs $50 to $110. Replacing both at once can run roughly $120 to $230, depending on location and part choice.
Air filters protect the engine and the interior from dust, pollen, and debris. In the Acura RDX, two filters perform these jobs: the engine air filter and the cabin air filter. Costs vary by whether you choose OEM or aftermarket parts, who performs the service, and the model year of your vehicle.
Understanding the two air filters in the Acura RDX
The Acura RDX uses both an engine air filter and a cabin air filter, each located in different parts of the vehicle and requiring different access methods. Replacing them is a relatively quick service, but prices differ for parts and labor.
Engine air filter
The engine air filter sits in the intake box in the engine bay. Manufacturers typically recommend checking or replacing it at intervals listed in the owner's manual, commonly around 30,000 miles or more, depending on driving conditions (dusty roads, heavy traffic, etc.).
Cost components for engine air filter replacement are typically as follows:
- Parts: OEM about $25–$40; aftermarket about $8–$25.
- Labor: Dealer/steering shop approach about $70–$95; independent shop about $40–$70.
- Typical total: about $70–$120.
Prices vary by location and whether you provide your own part or opt for the original equipment manufacturer part. Replacing the engine air filter yourself can cut the cost further if you’re handy.
Cabin air filter
The cabin air filter sits behind the glove compartment or under the dash, depending on the year and trim. It replaces more often in areas with high pollen or dust. The cabin filter life is typically shorter than the engine filter, often around 15,000–30,000 miles in many driving conditions.
Cost components for cabin air filter replacement are typically as follows:
- Parts: OEM about $20–$50; aftermarket about $8–$25.
- Labor: Dealer about $50–$90; independent shop about $30–$60.
- Typical total: about $50–$110.
Again, prices vary by location and whether the job is done at a dealership or an independent shop. DIY replacement for the cabin filter is usually straightforward and can save money.
Do-it-yourself vs professional service
For many owners, replacing the engine air filter is a quick DIY task that can save roughly $30–$60 in labor. For the cabin filter, the job is similarly simple on most RDX models, though some years require removing a panel or the glove box for access. If you’re unsure about the process, a quick visit to a nearby shop for guidance or a quick replacement can be cost-effective.
How to get precise quotes
To get an exact number for your specific car, year, and location, contact your local Acura dealer and several independent shops for itemized quotes. If possible, specify whether you want OEM or aftermarket parts and whether you’ll supply the part yourself.
Summary
In summary, engine air filter replacement typically costs around $70–$120 at a shop, and cabin air filter replacement usually runs about $50–$110. Replacing both filters together generally falls in the $120–$230 range, depending on part choice and labor rates. Doing the work yourself can lower costs, but you should be comfortable with the access requirements for each filter.
