Checked on every oil change, no extra charge. Photo before/after sent to your phone. OEM-equivalent or genuine OEM. From $45 installed.
A dirty engine air filter quietly costs you fuel economy and engine life. At Beacon Auto Care in San Mateo, we visually inspect the filter on every oil change and during any diagnostic visit. If it's saturated with debris, we send you a photo and a quote. Your call whether to replace today or next visit.
When to Replace
- Every 12,000–15,000 miles for most makes, the manufacturer recommendation.
- Visibly clogged with debris. If you can't see daylight through the filter material, it's time.
- MPG dropping for no obvious reason. A clogged filter is one of the cheapest fuel-economy fixes.
- Rough idle or sluggish acceleration. Restricted airflow can mimic ignition issues.

From a recent inspection: "Air Filter: Very Dirty with a lot of debris in it, recommend to replace immediately. Engine air filters should be changed every 12-15k miles on average to provide clean air and proper airflow for the engine to maintain good fuel economy and performance." Photo went to the customer's phone. The decision was theirs.
