MANN-FILTER WK 820/14 Fuel Filter with Heating Element is an OE-style replacement that protects fuel delivery in modern diesel systems. MANN-FILTER, part of the German MANN+HUMMEL group, is known for precise engineering and reliable filtration. This unit combines a high‑efficiency filter element with a built‑in heating element to improve fuel atomization and cold‑start performance. Note: check the original filter part number before buying, as mixed installation occurred from the factory.

It functions by filtering impurities from the fuel before they reach the pump and injectors, preserving engine performance and starting reliability. Contaminants, varnish, or water can clog filters over time, causing reduced fuel pressure, rough idle, or diminished power. Replacing with WK 820/14 restores clean flow and aligns with OE/OEM expectations for select European vehicles.
