MANN‑FILTER Fuel Filter WK 820/18

The WK 820/18 is a high‑performance fuel filter engineered by MANN‑FILTER for passenger cars and light commercial vehicles. Designed to protect the engine’s fuel system, it removes contaminants that can damage injectors, pumps, and other critical components.

Key Design Features

• Advanced Filtration Technology: Combines a multi‑layer filter media with a fine‑mesh screen to capture particles as small as 0.5 µm, ensuring clean fuel delivery.
• Durable Construction: Made from high‑grade polypropylene housing that resists corrosion and chemical attack, extending the filter’s service life.
• Low Pressure Drop: Engineered to maintain optimal fuel pressure, minimizing impact on engine performance and fuel economy.
• Heat‑Resistant Design: Capable of operating in temperatures up to 200 °C, suitable for high‑performance engines.
• Easy Installation: Standard 86 mm diameter fitting with a quick‑release clamp system, compatible with most OEM and aftermarket fuel lines.

Compatibility Overview

The WK 820/18 is specifically calibrated for a wide range of vehicle models. While the product name remains consistent across languages—MANN‑FILTER Kraftstofffilter WK 820/18, MANN‑FILTER Filtro de combustible WK 820/18, etc.—the underlying specifications are identical.

Installation Procedure

1. Safety First: Disconnect the battery and relieve fuel system pressure to prevent accidental spray.
2. Remove Old Filter: Unscrew the existing filter housing, allowing any residual fuel to drain into a container.
3. Prepare New Filter: Remove protective seal from the WK 820/18 and inspect for damage. Do not bend or compress the filter media.
4. Mounting: Insert the new filter into the housing, ensuring it sits flush with the mounting flange.
5. Secure Connections: Tighten all clamps to manufacturer specifications (typically 12 Nm torque).
6. Re‑pressurize System: Reconnect battery and restore fuel pressure. Check for leaks around the filter connections.

Maintenance & Replacement Interval

The WK 820/18 is designed to last up to 30,000 km or 36 months, whichever comes first. However, drivers should monitor fuel consumption and engine performance; any noticeable drop may indicate filter clogging.

Recommended Replacement Schedule

• High‑Mileage Vehicles: Replace every 20,000 km.
• Heavy‑Duty or Diesel Engines: Replace every 15,000 km.
• Standard Passenger Cars: Replace every 30,000 km.

Benefits to Vehicle Performance

• Engine Protection: Prevents abrasive particles from reaching fuel injectors and pumps.
• Improved Fuel Efficiency: Maintains optimal fuel flow, reducing consumption by up to 1–2 %.
