Parts for your 2015 Subaru Impreza-Wiper refills

2015 Subaru Impreza wiper refills — relevance, purpose, and servicing tips

Wiper refills are relevant and used on the 2015 Subaru Impreza. Subaru’s own technical literature allows for replacing the windscreen wiper blade rubber (refills) rather than the entire blade assembly, and the Subaru parts catalogue lists dedicated rubber refills for the GP/GJ-series Impreza (2012–2016). This aligns with common workshop practice in Australia and New Zealand, and is also supported by local application guides from major wiper manufacturers that specify refill inserts for this model. In short, the 2015 Impreza is designed to accept proper wiper refills where the blade type allows.

For the 2015 Subaru Impreza, wiper refills do the simple but vital job of keeping the windscreen clear. They’re the rubber inserts that slide into the blade frame, making direct contact with the glass to sweep away rain, road grime, and salt spray. Refills are a cost-effective way to keep visibility sharp without binning the entire blade assembly, and Subaru’s factory blade frames are commonly refillable.

Because Aussie and Kiwi conditions are tough on rubber — think harsh UV, dust, and coastal air — the wiper rubbers harden and streak more quickly. A good rule is to inspect every service and replace every 6–12 months, or sooner if there’s chatter, smearing, splits, or a greasy film that won’t clean off. Regularly wiping the edges with a damp cloth and a splash of mild soapy water (or a little isopropyl on a rag) keeps them working quietly.

Common sizes for many 2015 Impreza variants are around 650 mm (26 in) on the driver’s side and 400 mm (16 in) on the passenger side, with a rear refill near 300–305 mm (12 in) on hatch models. Sedans typically don’t have a rear wiper. Profiles and widths vary (often 6 mm or 8 mm), so matching the insert to the blade is key. Subaru’s owner’s manual and parts listings, plus reputable ANZ wiper catalogues, are the go-to for confirming fitment by body style and trim.

If tackling it at home, take care not to let the wiper arm snap onto the glass. Slide the old rubber out, transfer any stainless rails if required, and ensure the new refill locks into the end claws of the blade. Give the system a quick wet test. Note that some one-piece beam-style aftermarket blades aren’t designed for refills, in those cases, replace the whole blade assembly. For many OE-style frames on the 2015 Impreza, though, fresh refills keep the view crisp and the cost down.

• Inspect at every service, replace 6–12 months or at first sign of streaking.
• Clean the rubber and glass regularly for quieter, clearer wiping.
• Verify length, width, and profile against Subaru specs or trusted ANZ guides.

What size wiper refills fit a 2015 Subaru Impreza?

Many 2015 Impreza models use about 650 mm (driver) and 400 mm (passenger) refills, with hatchbacks often running a 300–305 mm rear. The insert width/profile can differ (commonly 6 mm or 8 mm), so it’s smart to check the blade style and confirm against Subaru’s parts info or a local ANZ application guide.

Body style matters: hatch vs sedan, and some trims may have different blade types. If in doubt, measure the old insert and take note of the rail style before buying.

How often should wiper refills be replaced on a 2015 Subaru Impreza?

Plan on every 6–12 months in Australia and New Zealand, thanks to UV, heat, and coastal air. Replace sooner if there’s streaking, judder, or cracking, or if the edge feels hard or nicked.

Cleaning the rubber and windscreen monthly helps extend life, but once performance drops off, fresh refills make a big difference to wet-weather vision.

Can universal refills be used, or should they be genuine Subaru?

Both can work. Genuine Subaru refills match the blade profile perfectly and tend to be quiet and precise. Quality aftermarket refills are fine if the width and claw profile suit the existing blade and rails.

If your Impreza has aftermarket one-piece beam blades that don’t accept inserts, you’ll need full replacement blades instead of refills.
