Quick answers about this car.
What size wipers fit a 2026 BMW 840i?
The 2026 BMW 840i takes 25" driver-side and 17" passenger-side wiper blades.
What connector does the BMW 840i wiper arm use?

Can I use a wiper blade one size longer or shorter?

Most drivers change them every 6 to 12 months. Swap them sooner if they start to streak, chatter, or miss spots.
