Parts for your 2016 Subaru Impreza-Air filter

2016 Subaru Impreza Air Filter

Technical sources confirm the 2016 Subaru Impreza is fitted with an engine air filter (air cleaner element). The Subaru Impreza Owner’s Manual for MY2016, the Subaru Service Manual for the FB-series 2.0L engine (intake/air cleaner section), and Subaru genuine parts catalogues all list and illustrate the air cleaner housing and replaceable element, as well as a separate cabin/pollen filter for the HVAC. So, an engine air filter is absolutely relevant and used on this model.

This air filter is the Impreza’s first line of defence against dust, sand, insects, and general road grit getting sucked into the engine. Keeping that stuff out protects the cylinders and sensors, helps the FB20 engine breathe properly, and supports good fuel economy and smooth power. In Aussie and Kiwi conditions—think unsealed roads, coastal air and seasonal dust—this little component does a big job.

Good servicing practice is to inspect the air filter at every service and replace it at sensible intervals. Subaru’s guidance is to check regularly and replace as needed, a practical rule of thumb is around 30,000–45,000 km or 2–3 years for typical urban/highway use. If the Impreza spends time on gravel, in the outback, or near the beach, expect more frequent changes—often every 15,000–20,000 km. A quick look under the bonnet at the air box (secured with clips or screws) will reveal the filter’s condition. If it’s dark, clogged, or shedding, it’s due.

Why bother? A clean filter helps the engine’s airflow readings stay accurate, reducing the chance of rough running and high fuel use. It also lowers the risk of dirt scoring the cylinder walls or contaminating the mass airflow sensor. Owners chasing consistent performance and economy will find an on-time filter swap is cheap insurance.

When replacing, choose a quality element that matches OEM specs. Fitment is straightforward: open the air box, note the orientation, seat the new element evenly, and ensure the lid seals properly. Avoid compressed-air “blow outs”—they can damage the media and force dirt deeper into the fibres. If the old filter looks dusty but serviceable, a gentle tap to dislodge loose debris is fine, but replacement is the safe bet once it’s noticeably discoloured or the car feels breathless.

• Common signs it’s time: sluggish acceleration, higher fuel use, induction noise change, or a visibly dirty element.
• Pair the engine filter change with checking the cabin filter for fresher air inside the car.

How often should the 2016 Subaru Impreza engine air filter be replaced?

For most city and highway driving in Australia and New Zealand, replacing every 30,000–45,000 km (or every 2–3 years) works well, with a quick visual check each service. If the car sees dusty roads, farm tracks or frequent coastal driving, shorten that to roughly every 15,000–20,000 km.

Always go by condition—if the element looks clogged or the car feels a bit breathless, it’s time.

Where is the engine air filter on a 2016 Impreza, and can owners change it themselves?

It sits in the air box under the bonnet, typically a black plastic housing with clips or screws on the intake side. Most owners can swap it in a few minutes with basic tools. Open the air box, lift out the old element, seat the new one the same way, and make sure the lid seals evenly.

Is the engine air filter the same as the cabin filter?

No. The engine air filter protects the engine from dust and debris, the cabin (pollen) filter cleans the air you breathe inside the car. They’re in different locations and have different jobs—both worth maintaining on schedule for a happier drive and healthier car.
