Parts for your 2018 Subaru Impreza-Wiper blades

2018 Subaru Impreza wiper blades — purpose, care, and when to replace

Yes, wiper blades are absolutely fitted to the 2018 Subaru Impreza. This is confirmed by the Subaru Impreza Owner’s Manual (MY2018) sections on wiper and washer operation and maintenance, the Subaru Genuine Parts Catalogue for 2018 which lists front and (for hatch models) rear wiper blade assemblies, and Subaru’s Service and Warranty guides that include blade inspection and replacement as routine service items.

On a 2018 Subaru Impreza, the wiper blades do the simple but vital job of keeping the windscreen clear of rain, road grime, coastal salt spray, and bug splatter so visibility stays sharp. In Aussie and Kiwi conditions—think high UV, hot summers, alpine frosts, and the odd muddy back road—the rubber edges work hard and naturally wear. That’s why regular inspection and timely replacement of the 2018 Subaru Impreza wiper blades is part of sensible servicing.

As a rule of thumb, most drivers will be best off replacing blades every 6–12 months, or sooner if there’s streaking, smearing, squeaks, juddering, or if the edge looks nicked or glazed. Cleaning helps extend life: a quick wipe of the blade edge with a damp cloth and mild car-wash solution (or an isopropyl wipe) and keeping the windscreen clean reduces grit that chews out the rubber. For hatch models with a rear wiper, don’t forget that little blade—rear visibility matters in wet city traffic just as much as on the open road.

Fit quality blades that match the factory style and lengths for the Impreza. Driver and passenger sides are different, and the hatch’s rear blade is unique again, so check the owner’s manual or a trusted parts catalogue. Many 2018 Impreza models feature Subaru EyeSight driver assist with cameras behind the screen, correct blade length and a clean sweep area help keep the cameras’ view unobstructed. Swapping blades won’t affect EyeSight calibration, but after any windscreen replacement the camera system may need professional calibration.

Handy care tips:

• Clean the rubber edges and windscreen monthly, top up proper washer fluid, not just water.
• Avoid dry-wiping, use the washers to lubricate before wiping stubborn grime.
• In frost, lift blades gently to free them—don’t yank or pour hot water on the glass.
• When installing, protect the glass if the arm is lifted, follow the adaptor’s instructions.

Done right, fresh wiper blades make wet-weather driving calmer, safer, and a whole lot less tiring.

FAQs

What size wiper blades fit a 2018 Subaru Impreza?

Sizes vary by body style and market. The driver’s side is longer than the passenger’s, and hatch models use a different rear blade. The easiest way to be sure is to check the owner’s manual or a reputable parts catalogue for the exact trim, or measure the existing blades and match like-for-like.

How often should wiper blades be replaced in Australia or New Zealand?

Plan on every 6–12 months. High UV, salt air near the coast, dust, and big temperature swings can harden or crack the rubber faster, so if there’s any streaking, chatter, or hazing, replace them sooner rather than later.

Can wiper blade replacement affect Subaru EyeSight?

Swapping the blades themselves won’t affect EyeSight. Just fit the correct lengths so the cameras have a clear, full sweep of the windscreen. If the windscreen is replaced, that’s when EyeSight may require a professional camera calibration.
