Original MANN-FILTER Oil Filter WK 842/20 – For passenger cars

Product Overview

The MANN‑FILTER Oil Filter WK 842/20 is a high‑performance oil filter engineered for passenger cars. Designed to meet stringent automotive standards, it delivers reliable protection for the engine’s lubrication system by capturing contaminants and maintaining optimal oil quality.

Key Design Features

• Advanced Filter Media: Utilizes a multi‑layer filtration matrix that captures particles as small as 0.5 µm, ensuring clean oil flow to critical engine components.
• Robust Construction: Encased in a durable polypropylene housing with reinforced seals, the filter resists cracking and maintains integrity under high pressure and temperature conditions.
• Optimized Flow Rate: Engineered to provide low resistance while maintaining sufficient oil flow, thereby preserving engine performance and fuel efficiency.

Compatibility & Application

The WK 842/20 is specifically tailored for a wide range of passenger car engines. Its dimensions (Ø 101 mm) and mounting design allow seamless installation in most standard oil filter brackets. The filter’s specifications align with OEM requirements, making it an ideal replacement or upgrade for vehicles seeking superior filtration.

Performance Characteristics

The MANN‑FILTER Oil Filter WK 842/20 excels in several critical performance areas:

• Contaminant Retention: Capable of trapping up to 99.9% of oilborne particles, protecting bearings, pistons, and camshafts from wear.
• Pressure Drop Management: Maintains a pressure differential below 0.5 bar across typical operating ranges, ensuring consistent oil delivery.
• Thermal Stability: Withstands temperatures up to 200 °C without degradation of filter media or housing integrity.

Longevity & Maintenance

Designed for extended service intervals, the WK 842/20 can operate effectively for up to 10,000 km under normal driving conditions. Regular inspection and timely replacement are recommended to preserve engine health and avoid potential oil starvation scenarios.

Installation Guide

1. Preparation: Warm the engine to operating temperature; drain existing oil if necessary.
2. Removal: Unscrew the old filter carefully, allowing any residual oil to drip into a container.
3. Sealing: Inspect the rubber gasket for wear; replace if damaged. Apply a thin layer of fresh engine oil onto the new gasket to ensure an airtight seal.
4. Mounting: Align the filter housing with the mounting bracket and tighten securely, following manufacturer torque specifications.
5. Final Check: Refill engine oil to the recommended level and start the engine. Observe for leaks and verify proper operation.

Troubleshooting Common Issues

• Oil Leak: Verify gasket integrity; ensure correct torque application.
• Reduced Oil Pressure: Check for clogged filter media or incorrect installation orientation.
• Unusual Engine Noise: Inspect for oil starvation due to a blocked filter; replace immediately if detected.

Benefits of Choosing MANN‑FILTER WK 842/20

• Engine Protection: By removing contaminants, the filter prolongs engine life and reduces maintenance costs.
• Fuel Efficiency: Low resistance flow preserves optimal oil pressure, contributing to better fuel economy.
• Reliability: Proven performance in diverse driving conditions ensures peace of mind for vehicle owners.
• Environmental Impact: Cleaner oil reduces emissions and supports compliance with stringent environmental regulations.
