WK 820/18 Fuel Filter for Mercedes Benz GLK200 Sprinter E250 2006 2020 2.1L 3.0L

Product Overview

The WK 820/18 Fuel Filter is designed to remove water, dirt, and fine particles from diesel fuel before they reach the high-pressure injection system. Using the WK 820/18 fuel filter protects expensive common-rail injectors and the high-pressure pump from premature wear and failure. This WK 820/18 fuel filter is a direct replacement for the specified Mercedes-Benz diesel platforms and maintains factory filtration performance.

Key Features & Performance

• Premium multi-layer cellulose and synthetic fiber media captures microscopic contaminants and water droplets.
• Direct drop-in replacement — identical fit, port configuration, and sealing surfaces as the original filter.
• High dirt-holding capacity extends service intervals even in stop-and-go fleet operation.
• Rigid, corrosion-resistant end caps and center tube prevent collapse under high fuel flow demands.
• Stable filtration efficiency across the entire service life, not just at the beginning.

Fitment & Compatibility

• 2006–2020 Mercedes-Benz GLK200 (2.1L / 3.0L CDI diesel engines)

• 2006–2020 Mercedes-Benz E250 (2.1L / 3.0L CDI diesel engines)

Common Uses

• Scheduled fuel filter replacement on Mercedes diesel passenger cars and light commercial vehicles to maintain warranty compliance.
