Mike Shaw Subaru provides up-front pricing before work begins in Thornton, Colorado.

• Replacement parts are matched to the vehicle’s engine specifications.
• Both filters can be checked during one visit.

Mike Shaw Subaru can inspect the filter and housing when the vehicle reaches that interval.

A restricted engine filter can reduce airflow, fuel economy, and throttle response.

• Replacement interval: every 30,000 miles.
• Inspection includes the engine air filter housing.
• Restricted airflow may affect drivability.

• Engine filter: engine bay filter housing.
• Cabin filter: typically behind the glove box.

• Engine filter: protects the combustion intake.
• Cabin filter: supports passenger-compartment air quality.

Local road dust and seasonal airborne debris can collect in filter media and reduce airflow. Drivers may notice lower fuel economy or a duller throttle response when the engine filter is restricted. Inside the cabin, weak ventilation or a dusty or musty smell can point to the cabin filter. A visual inspection can also reveal a filter that looks grey or packed with debris.

The maintenance intervals matching the 2023 and 2025 models call for cabin air filter replacement every 12,000 miles and engine air filter replacement every 30,000 miles. Mike Shaw Subaru is located at 1650 W 104th Avenue in Thornton. Call 720-724-9280 or schedule service.

The cabin air filter is inspected separately, along with the cabin intake path.

When replacement is needed, both filters can be handled during the same visit so the vehicle’s engine intake and passenger HVAC filtration receive attention together.

The schedule matching the 2023 and 2025 models calls for the cabin filter every 12,000 miles and the engine filter every 30,000 miles. To arrange service at Mike Shaw Subaru, call 720-724-9280 or schedule service.

For maintenance planning, the intervals matching the 2023 and 2025 models call for cabin air filter replacement every 12,000 miles and engine air filter replacement every 30,000 miles.
