The 2018 Honda CR-V uses two dedicated air filters: one engine air filter and one cabin air filter. Both play a crucial role in protecting the engine and maintaining interior air quality, with replacement needed on a regular maintenance schedule.
What filters are in the 2018 CR-V?
The 2018 CR-V is equipped with two primary air filtration components. The following sections explain each filter, its purpose, where to find it, and general replacement guidance.
Engine air filter
Overview: The engine air filter cleans the air that enters the engine for combustion, helping maintain performance and efficiency. Location: It sits in the engine's air intake box, typically accessible from the top or side of the engine bay depending on the variant (2.4L or 1.5L turbo in some trims). Replacement: A typical interval is around 30,000 miles, though inspection is advised and conditions such as dusty roads may require earlier replacement.
Important notes: If you notice a drop in power, rough idle, or reduced fuel economy, have the engine air filter checked. Always refer to the owner's manual for your exact engine configuration and recommended maintenance schedule.
- Access and replacement: The filter is inside a plastic housing with clips or screws. Unclip/unscrew the housing, replace the filter, and reseal the cover.
- Maintenance tip: Inspect during routine service; a dirty filter can restrict airflow and reduce engine performance.
Replacing the engine air filter on schedule helps protect the engine and maintain fuel efficiency. Check your manual for the precise interval for your engine variant and driving conditions.
Cabin air filter
Overview: The cabin air filter cleans air entering the passenger compartment through the HVAC system, improving interior air quality and odor control. Location: It is typically located behind the glove box or under the dashboard, depending on trim level. Replacement: Common guidance is about 15,000 miles or roughly once a year, with more frequent changes in dusty or high-pollen areas.
Important notes: A clogged cabin filter can reduce airflow from the HVAC system and allow odors to linger indoors. Always follow the specific interval recommended in your owner's manual for your trim and climate.
- Access and replacement: Access usually involves removing the glove box or panels to reach the filter housing, then sliding out the old filter and inserting a new one with the correct orientation.
- Maintenance tip: If you or passengers suffer from allergies or you drive in dusty areas, consider replacing the cabin filter more frequently.
Keeping the cabin air filter fresh improves HVAC efficiency and interior air quality, aligning with the vehicle’s overall maintenance schedule.
Summary
In short, the 2018 Honda CR-V has two air filters—one for the engine and one for the cabin. Typical replacement guidelines are about 30,000 miles for the engine filter and about 15,000 miles (roughly once a year) for the cabin filter, with adjustments for driving conditions. Always consult the owner's manual or a Honda service professional for your specific vehicle configuration and maintenance plan.
