Great fit...but 1" shorter
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Fit and quality is great. However the shortblade needs to be 21". OEM is26" and 21". Bosch sets 26 and 20". I may have missed, but I didnt t see anyone mentioning this issue.
Other than that is perfect fit.

Terrific Bosch blades
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
These German made wiper blades do their job so well that my wife was impressed. Once you get the hang of it they are one minute to replace. Recommend placing a cloth under the blade to avoid any windshield scratches if the metal wiper assembly accidentally falls down on the glass. Nice to see the Bosch name on the wiper blades.

Best replacement option for 2025 Tesla Model Y Performance
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Outstanding replacement option for 2025 Tesla Model Y Performance (Pre-Juniper), so much smoother than the OEM wipers. Very easy to replace. They seem very durable after testing on all wiper settings. Definitely keep the windshield clearer without streaks. Seem to also have more stability on mounting compared to OEM option. 15/10 replacement for the cost, can’t beat it.
