OEM Subaru Air Filters

Refine Results

Don't underestimate the importance of air filters for a Subaru. Your vehicle has two types: an engine air filter and a cabin air filter. They help make sure the many parts of your engine and HVAC continue to work right. What does each air filter do and how does it work? Engine filters trap airborne particles before they can accumulate on your throttle body's air intake, your fuel injectors, and spark plugs, among other components. Cabin filters catch them before they can build up in the ducts and on the vents and fans of your heater and air conditioning systems. Both do that using pleated cotton, synthetic paper, or foam fibers. If your Subaru didn't have either, all that buildup would start wear out those parts fast. Unfortunately, even the high-quality air filters made by your OEM don't last forever. They eventually clog and decay with age, and when they get congested, more trouble results. Engine air filters full of debris lead to increased emissions, lower gas mileage, engine misfires, and other engine problems. Dirty cabin air filters choke airflow, stressing your engine and causing heating and air conditioner malfunctions. You can prevent this. Simply change your air filters regularly. Wondering when exactly to replace them? Check your owner's manual's filter maintenance schedule. You usually do it every 12,000 to 15,000 miles or so. There are signs to tell you when you should. They include a lit Check Engine light, damaged fibers, built-up crud, abnormal engine noise, bad cabin smells, and excessive exhaust smoke. If you're seeing those symptoms, it's probably time to buy new air filters. Be sure to order genuine Subaru. Air filters from your brand's factory will fit your model best. Luckily, you can get them online at our auto parts store. Buy now!
