• Thread Size: 12 mm (M12) – ensuring secure attachment to the fuel line.
• Material Composition: High‑grade cellulose and synthetic fibers combined with an advanced filtration matrix that captures particles down to 5 µm.
• Flow Rate: Maintains a low pressure drop while allowing sufficient fuel flow for high‑performance engines.
• Certification: Meets or exceeds OEM specifications for fuel filtration, ensuring compatibility with engine management systems and emissions controls.

Performance Benefits

The WK 842/13 filter is engineered to deliver a series of performance advantages that translate into tangible benefits for vehicle owners:

• Enhanced Engine Protection: By trapping dirt, rust particles, and other contaminants, the filter prevents abrasive wear on fuel injectors, pumps, and combustion chambers.
• Improved Fuel Efficiency: Clean fuel flow reduces engine friction and improves combustion efficiency, potentially leading to better mileage.
• Reduced Maintenance Costs: A reliable filter decreases the likelihood of injector clogging and pump failure, extending service intervals.
• Consistent Performance Across Conditions: The filter’s robust construction ensures stable operation in both hot climates and high‑altitude environments where particulate matter may be more prevalent.

Installation & Maintenance Guidance

Installing the WK 842/13 is straightforward, yet precision is essential to maintain fuel system integrity. Follow these steps for optimal results:

1. Safety First: Disconnect the vehicle’s battery and relieve the fuel system pressure before removing the old filter.
2. Remove Old Filter: Unscrew the existing filter housing, allowing any residual fuel to drain safely into a container.
3. Prepare New Filter: Inspect the new WK 842/13 for any packaging damage. Do not bend or compress the filter media.
4. Install: Place the filter in the housing, ensuring it sits flush against the mounting surface. Tighten to the manufacturer’s torque specification (typically 12 Nm).
5. Re‑pressurize & Test: Reconnect the battery, restore fuel pressure, and check for leaks. Verify that engine idle is stable before driving.

For routine maintenance, replace the filter every 30,000 km or as recommended by the vehicle’s service schedule. Early replacement in high‑contamination environments (e.g., dusty roads) can further safeguard engine health.

Compatibility Overview

The WK 842/13 is designed to fit a broad spectrum of passenger car models, particularly those that use inline petrol engines with standard fuel filter housings. While the filter’s dimensions and thread size are universal, it is advisable to confirm compatibility with your specific vehicle model before purchase.

Common Vehicle Families

• Mercedes‑Benz: A‑Class (W168), V‑Class, Sprinter, Vito – all models equipped with inline petrol engines.
• Nissan: Select passenger cars featuring inline fuel systems.
• Other European Brands: Many compact and mid‑size vehicles from German and Italian manufacturers share the same filter specifications.
