I just installed Bosch Icon 26OE and 21OE, fits perfect (use the number 4 adapter). My stock blade on passenger side (on a Macan 4) was measured actual 21 inch.
Wondering if you have tried these 26/22 size? My originals are streaking bad, but I measure 26/21 on my Macan 4. Worried the 22 passenger side would rub against the windshield frame? Thanks
