Subaru 16546AA12A Genuine Engine Air Filter — for Select Subaru Models

A clogged or dirty engine air filter restricts airflow, potentially causing a decrease in engine power, sluggish acceleration, and reduced fuel economy. This can also lead to premature wear of the mass airflow sensor and other engine components. Replacing it with this genuine Subaru air filter restores clean airflow and ensures optimal engine performance and protection.

This is a factory-original Subaru engine air filter (OE part number 16546AA12A). It is manufactured to Subaru’s strict specifications, ensuring a perfect fit and reliable performance. This is the same part sold at Subaru dealerships.

 

When to Replace

FAQ

FAQ

Is this a genuine Subaru part or a copy?
This is 100% genuine Subaru OEM — in original factory packaging with Subaru part number printed on the label. It is not an aftermarket brand or a replica .

Yes — the 2015 WRX with the 2.0L or 2.5L engine uses this air filter . We recommend verifying with your VIN.

Does this fit the Subaru Forester?
Yes — the Forester (2009–2018) with the 2.5L engine is compatible with this filter . Please verify with your VIN.

Can I use an aftermarket filter instead?
This is a genuine OEM part. Aftermarket equivalents (e.g., K&N 33-2304, WIX 46914) are available, but this listing is for the genuine Subaru part .

What is the recommended change interval?
Typically, 15,000–30,000 miles depending on driving conditions . Check your vehicle’s service manual for the exact schedule.

How do I install this filter?
Open the air box, remove the old filter, clean the inside of the air box, and insert the new filter. Ensure it is seated correctly before closing the cover .

Does this filter come with a gasket?
