Product Details

The Bosch OE Style Blade line focuses on direct-fit replacement coverage for vehicles that use an original-equipment style front wiper setup. Part number 3397118938 is listed for front applications on Mercedes-Benz C300, C250, C350, C63 AMG, E300, E350, E400, E550, E63 AMG, E63 AMG S, CLS550, CLS63 AMG, and CLS63 AMG S models within the stated year ranges.

What It Helps Address

• Streaking across the windshield
• Uneven wiping on the driver and passenger sides
• Chatter or skipping during operation
• Reduced visibility from worn rubber edges
• Poor glass contact on OE-style front wiper systems

Installation Notes and Tips

Verify the vehicle’s front wiper configuration and match the listed year, make, model, and notes before ordering. This Bosch 3397118938 set does not include adapters or quick-connect hardware, so confirm the existing OE-style attachment matches the blade connection on the vehicle. For best results, inspect the windshield for debris or buildup before installing new blades.
