To anyone using the Bosch Icon wipers on a 4th Gen, what sizes do you have? 22A for the driver side is pretty obvious, but both Amazon and Bosch suggest 20A for the passenger size, not the "B" version that would normally be for the passenger side. Is that right?
The A vs B designation has to do with the spring tension of the wiper blade. If you use the wrong one it may not have enough tension to make full contact along the entire length of the blade due to the curvature or the windshield. That being said Bosch specs “A” for both sides. I got A’s for both sides and they work perfect.
