Mann Filter fuel filter WK 820/15 for Mercedes‑Benz Sprinter (no fuel heating) — MULTIGRADE F, water separation

The MANN-FILTER WK 820/15 is a high-efficiency replacement fuel filter designed to protect select Mercedes‑Benz Sprinter engines without the integrated fuel heating option by removing contaminants and separating water from diesel.

Modern diesel injection systems demand clean, dry fuel to preserve injectors, pumps and sensors. The WK 820/15 uses advanced MULTIGRADE F filter media and premium construction to trap dust, rust and dirt while delivering near-complete fuel/water separation, helping maintain reliable fuel flow and consistent engine performance under a range of conditions.

How does this filter protect my Sprinter's fuel system?

The filter captures particulates and separates water before fuel reaches the injection components, reducing wear on high-precision parts. Its engineered media and housing maintain optimal flow with minimal pressure loss so the fuel pump and injectors operate within design tolerances.

• High-efficiency MULTIGRADE F media traps fine dust and rust particles.
• Almost 100% fuel/water separation in diesel testing to prevent corrosion.
• Robust materials resist extreme temperatures and extended service intervals.

Will this part fit my Mercedes‑Benz Sprinter?

This WK 820/15 is compatible with select Mercedes‑Benz Sprinter models that do not have the integrated fuel heating option. Always cross-check the OE numbers and your vehicle’s requirements before purchase to ensure correct fitment.

• Check OE references A 642 090 63 52 and A 642 090 64 52 for compatibility.
• Designed for Sprinter variants without factory fuel heating systems.
• Confirm fit with your vehicle build year and engine code.

How easy is installation and replacement?

Installation follows standard fuel filter replacement procedures and is accessible on Sprinter models with the correct mounting arrangement. Replacement intervals depend on operating conditions, but the durable design supports longer service life compared with lower-grade alternatives.

• Swap-in design with OE-quality fitment for straightforward installation.
• Durable construction reduces frequency of replacements in normal use.
• Follow vehicle manual and safety practices when changing fuel filters.

What performance benefits can I expect after fitting this filter?

Using a high-quality fuel filter like the WK 820/15 helps preserve fuel system components, sustain consistent fuel flow and reduce the risk of injector fouling. While not a performance enhancer by itself, it supports dependable engine operation and can help avoid fuel-related faults.

• Cleaner fuel delivery reduces injector wear and maintenance events.
• Stable pressure and flow characteristics protect sensitive electronics and pumps.
• Improved water separation lowers corrosion and microbial growth risk in fuel lines.

Who is this for? The MANN-FILTER WK 820/15 is aimed at Sprinter owners, fleet managers and independent technicians seeking an OE-quality replacement fuel filter for Mercedes‑Benz Sprinter models built without integrated fuel warming. If you prioritize reliable filtration, effective water separation and long service life from a globally recognized filtration specialist, this filter offers a direct-fit solution engineered to protect modern diesel injection systems.
