I purchased the BOSCH H309 OE Specialty rear wiper blade as a replacement, and it fit perfectly. Installation was quick and easy, and it snapped right into place without any issues. The wiping performance is excellent. It clears the rear window smoothly and evenly, with no streaking or skipping. Even in heavier rain, it does a great job keeping the glass clean and clear. The build quality feels solid, which is what I expect from Bosch. After regular use, it’s still performing well and hasn’t shown any signs of wear. Overall, this is a high-quality rear wiper blade that works exactly as intended. Easy to install, great performance, and reliable quality. I would definitely buy it again.

Great Pick

Size: H326 (13")

Fits perfect for my 2006 Hyundai Santa Fe. Doesn’t leave streaks and doesn’t make much noise compared to my old one. Had an awful storm and it kept up well and was shockingly durable. It offers good coverage on the rear windshield and is clear enough that I can still see.
