• Model Code: WK 42/5 – a designation that identifies the filter’s size and compatibility profile.
• Material Composition: Premium synthetic media combined with a robust housing to resist pressure fluctuations and temperature extremes.
• Filtration Efficiency: Capable of removing particles as small as 0.3 microns, ensuring that engine oil remains free from contaminants that could cause wear or reduce performance.
• Flow Rate: Optimized to maintain a high flow rate, reducing the risk of pressure drop and preserving engine lubrication under all operating conditions.
• Installation: Straightforward, with a standard threaded connection compatible with most passenger car oil filter fittings. The design allows for quick removal and replacement without special tools.

Compatibility & Vehicle Coverage

The WK 42/5 is engineered to fit a wide range of passenger cars from various manufacturers. Its standardized dimensions and threading make it suitable for:

• Compact and mid‑size vehicles – ensuring that even smaller engines receive optimal protection.
• High‑performance models – the filter’s robust construction supports engines with higher horsepower and torque demands.
• Diesel and gasoline engines – its media is effective across both fuel types, providing versatility for owners who switch between engine configurations.

Performance Benefits

Choosing the MANN‑FILTER Oil Filter WK 42/5 offers several tangible advantages:

• Extended Engine Life: By trapping microscopic debris, the filter reduces internal wear and prolongs the lifespan of critical engine components such as bearings, pistons, and camshafts.
• Improved Fuel Efficiency: A clean oil system maintains optimal lubrication, which can lead to smoother engine operation and reduced fuel consumption.
• Consistent Oil Pressure: The filter’s design ensures that oil pressure remains stable even under high load or extreme temperatures, safeguarding the engine against potential damage.
• Reduced Maintenance Frequency: With superior filtration performance, owners can rely on longer intervals between oil changes without compromising engine health.

Installation Guide

1. Prepare the Vehicle: Warm up the engine to operating temperature to ensure that the oil is at its optimal viscosity. This helps prevent any blockage during filter removal.

2. Drain Excess Oil (Optional): While not always necessary, draining a small amount of oil can reduce pressure and make removal easier.

3. Remove the Old Filter: Use an appropriate wrench or filter tool to loosen the existing filter. Allow any residual oil to drain into a catch pan.

4. Inspect the Mounting Surface: Clean the flange area of any debris or old gasket material to ensure a proper seal with the new filter.

5. Install the WK 42/5: Place the new filter onto the mounting surface, aligning it correctly. Tighten by hand until snug, then give an additional quarter turn with the wrench to secure it without over‑tightening.

6. Check for Leaks: Start the engine and observe the filter area for any signs of oil leakage. If leaks are detected, re‑tighten slightly or replace the gasket if necessary.
