Original MANN-FILTER Oil Filter WK 822/4 – For passenger cars

MANN‑FILTER Oil Filter WK 822/4 – For Passenger Cars

The MANN‑FILTER Oil Filter WK 822/4 is a premium, OEM‑grade filtration solution designed specifically for passenger vehicles that require reliable protection of the engine’s lubrication system. Crafted with precision engineering and high‑performance materials, this filter delivers exceptional contaminant removal while maintaining optimal oil flow.

Key Features & Technical Highlights

• High‑Efficiency Filtration: Utilises a multi‑layer media construction that captures particles as small as 0.5 µm, ensuring the engine oil remains free from sludge, dirt, and metallic wear debris.
• Optimised Flow Resistance: Engineered to minimise pressure drop, this filter preserves engine efficiency by allowing smooth oil circulation under high‑temperature conditions.
• Durable Construction: Made with a robust polypropylene housing that resists cracking and deformation, guaranteeing long‑term performance even in demanding operating environments.
• Easy Installation: The spin‑on design fits standard filter housings without the need for additional tools or adapters. A secure seal is achieved through a tight, torque‑controlled mounting process.
• Compatibility: Specifically calibrated for a wide range of passenger cars, including models such as the KIA Sportage, Landini, and other OEM vehicles that call for the WK 822/4 specification.

Material Composition & Design Philosophy

The filter’s core is composed of a proprietary blend of synthetic fibers and natural cellulose. This combination offers:

• Superior Filtration Efficiency: The synthetic layer traps fine particulates, while the cellulose component provides excellent oil retention capacity.
• Thermal Stability: Both materials maintain structural integrity up to 200 °C, preventing filter degradation during engine start‑up and high‑load operation.
• Environmental Resilience: The polypropylene housing resists corrosion, UV exposure, and chemical attack from oil additives.

Performance Metrics & Testing Standards

The WK 822/4 filter undergoes rigorous testing in accordance with international automotive standards such as ISO 4406, DIN 51601, and SAE J1348. Test results consistently demonstrate:

• Particle Retention Rate: ≥ 99.9 % for particles > 0.5 µm.
• Pressure Drop: ≤ ¹ bar at a flow rate of 10 L/min, ensuring minimal impact on engine oil pressure.
• Oil Capacity: Maintains ≥ 90 % of the original oil volume after full filtration cycles.

Installation Procedure (Step‑by‑Step)

1. Preparation: Warm the engine to operating temperature. Drain a small amount of oil to relieve pressure, then remove the existing filter carefully.

2. Inspection: Check the filter housing for damage or debris that could compromise sealing.

3. Mounting: Place the new WK 822/4 filter onto the housing, aligning the mounting flange with the gasket. Ensure the filter is seated evenly.

4. Tightening: Use a torque wrench to secure the filter at the manufacturer’s recommended setting (typically between 10–15 Nm). Avoid over‑tightening to prevent housing cracks.

5. Reassembly: Reinstall any removed components, refill the engine with fresh oil, and start the vehicle. Check for leaks and verify that oil pressure returns to normal levels within a few minutes of operation.

Maintenance & Longevity Considerations

While the WK 822/4 filter is engineered for durability, regular maintenance schedules should still be observed:

• Oil Change Interval: Replace the filter at every oil change or as specified by the vehicle manufacturer’s service manual.
• High‑Mileage Vehicles: For engines that have exceeded 100,000 km, consider an earlier replacement to preclude potential contamination buildup.
• Extreme Conditions: In dusty or high‑temperature environments, a more frequent filter change may be warranted to maintain optimal oil cleanliness.

Benefits for Vehicle Performance and Longevity

The MANN‑FILTER WK 822/4 delivers tangible advantages that translate into real-world benefits:

• Engine Protection: By trapping contaminants, the filter reduces wear on bearings, pistons, and camshafts, extending engine life.
• Fuel Efficiency: A clean oil system maintains proper lubrication, reducing friction losses and improving fuel economy by up to 1–2 %.
• Reduced Emissions: Consistent oil quality helps the combustion chamber operate more efficiently, lowering exhaust emissions.
• Reliability: The filter’s robust design ensures consistent performance across a wide range of operating temperatures and driving conditions.
