Product Details

TRICO Exact Fit 21-12B is engineered to meet OE standards and specifications, making it a direct replacement choice for drivers who want the correct blade profile and connection style without modifying the arm. This part number is commonly searched for BMW i3 and i3s front right applications, as well as Mercedes-Benz GLK350, GLK300, GLK280, and GLK250 fitments, plus select Audi TT, Audi TT Quattro, Saturn Astra, and Volkswagen Passat and Phaeton positions. This part cross-references Bosch-style applications (e.g., 3 397 118 923, 3 397 118 925) for the same application.

What It Helps Address

• Streaking caused by worn or hardened wiper rubber
• Skipping or chatter across the windshield
• Poor contact from an incorrect blade length or connector type
• Reduced wiping consistency from aging conventional-frame blades
• Fitment issues on Side Pin (22mm) wiper arm applications

Installation Notes and Tips

Confirm the vehicle position, arm connection, and blade length before installation. This blade uses a Side Pin (22mm) connection with a pre-attached adapter, so it should be matched to the listed arm style on the vehicle.
