These Bosch blades are exact fit - no adapters required.

 

I swapped out my second set of OEM blades for the Bosch blades. While the chattering is noticeably reduced, it has not gone away completely. The blades could further improve after break-in, but the early results aren't what I had hoped for. Still, with better performance than OE blades at less than half the price, I would recommend you give the Bosch blades a try if you continue having stuttering problems after cleaning/polishing your windshield.

 

And ceramic detailing spray took care of the little chattering I was still experiencing. I tried this with the OE blades and it helped very little, but when used in conjunction with the Bosch blades I finally have wipers that work the way they're supposed to. Plus it's the best all around detailer I've ever used.

 

Bosch blades for the win. Purchased both fronts from Summit Racing all in for less than $40 (I did not change the rear).
