Parts for your 2014 Subaru Impreza-Air filter

2014 Subaru Impreza air filter — purpose, care, and when to replace

Yes, an engine air filter is absolutely fitted to the 2014 Subaru Impreza. This is confirmed by Subaru’s 2014 Impreza Owner’s Manual (Maintenance and Service section), the Subaru Service Manual (Engine > Intake), and Subaru’s parts catalogue, which list the “air cleaner element” as a service item for the FB20 2.0‑litre engine.

On this Impreza, the air filter’s job is to let the engine breathe clean air while trapping dust, pollen, and grit. Keeping debris out of the intake, throttle body, and cylinders helps maintain power, fuel economy, and smooth running, while reducing engine wear and emissions. It’s a simple, relatively cheap part that protects very expensive bits.

The filter sits inside the air cleaner box in the engine bay. Pop the clips, lift the lid, and you’ll find a rectangular panel filter. Most owners can swap it in 5–10 minutes. Go for a quality OEM-style dry paper element, it filters exceptionally well with no fuss. If using a reusable or oiled performance filter, follow the maker’s care instructions to the letter and don’t over-oil, as excess oil can contaminate the MAF sensor.

Service-wise, the owner can have it inspected at every routine service (roughly every 12,500–15,000 km), and replaced about every 30,000–45,000 km or every 2–3 years. In Aussie and Kiwi conditions—especially if driving on unsealed or rural roads—it’s smart to check more often and replace sooner if it looks dirty or performance drops.

• Tell-tales it’s due: dull acceleration, increased fuel use, rough idle, or a visibly dark, clogged filter.
• Quick check: hold the filter up to bright light, if light barely shines through, it’s time.
• Avoid blasting with high-pressure air or washing paper elements—this can damage the media.

Don’t mix it up with the cabin filter (that one cleans the air you breathe inside the car, behind the glovebox). The engine air filter is all about keeping the FB20 happy for the long haul—easy maintenance that pays off every time the driver hits the starter.

Popular questions about 2014 Subaru Impreza air filters

How often should the engine air filter be replaced?
For most drivers, every 30,000–45,000 km or 2–3 years works well, with an inspection at each service interval. If the car sees plenty of dusty gravel roads or summer road trips, expect to replace it sooner.

Where is the air filter located, and can it be changed at home?
It’s in the air cleaner box in the engine bay—rectangular housing with clips. Release the clips, lift the lid, swap the panel filter, and re‑seat the lid. It’s a simple 5–10 minute DIY. Be gentle around the nearby MAF sensor and make sure the airbox seal sits properly.

OEM vs performance filter—what’s best for a daily driver?
OEM-style dry paper filters offer excellent filtration and low maintenance—ideal for daily use. Performance filters can add induction sound and may flow more at high RPM, but some require careful cleaning and oiling, excess oil can upset the MAF. For most daily drivers, OEM or a high-quality dry aftermarket filter is the safest bet.
