I've been using wiper refills for years (don't laugh) but they continue to get harder to find. I'm probably going to try those Bosch ICON blade assemblies. My 06 specs 20 inch wipers but I'm debating on getting the 22" since there is plenty of clearance on the top and bottom for the extra 1". I'm wondering if this will cause an issue with the wiper motor. Has anyone done this already?
