What It Helps Address

• Streaking across the windshield during rain
• Skipped or chattering blade movement
• Uneven wiping caused by worn blade edges
• Poor contact on curved windshield surfaces
• Reduced visibility from aged front wiper blades

Installation Notes and Tips

Confirm the vehicle year, make, model, and front position before installation. This blade set does not include adapters or quick-connect hardware, so verify that the existing arm connection matches the OE-style blade interface on the vehicle. For 2009 Audi A4 and 2009 Audi A4 Quattro applications, the fitment notes state that the wiper blade is slightly shorter than the original part. For 2004 Audi A4, 2004 Audi A4 Quattro, and 2004 Audi S4 applications, the fitment notes specify use from 11/2003.
