Original MANN-FILTER Oil filter W 940/3 – For Passenger Cars

MANN‑FILTER Oil Filter W 940/3

The MANN‑FILTER Oil Filter W 940/3 is a premium filtration solution engineered for passenger cars that demand the highest level of engine protection and performance. Designed with precision engineering, this filter delivers superior oil cleanliness, ensuring optimal lubrication, reduced wear, and extended engine life.

Key Features

• Dual Anti‑Return Valves: The filter incorporates two high‑performance anti‑return valves that prevent backflow of contaminated oil. This design maintains a consistent flow path, protecting the engine from potential damage caused by reverse pressure.
• High‑Efficiency Media: Utilizing MANN‑FILTER’s proprietary filtration media, the W 940/3 captures particles as small as 0.5 µm with an efficiency of up to 99.9%. This level of filtration preserves engine integrity and improves fuel economy.
• Robust Construction: The filter housing is made from durable polypropylene, offering resistance against corrosion, high temperatures, and mechanical stress. Its robust design ensures reliable performance under demanding driving conditions.
• Standard Thread Size: With a 3/4‑16 UNF thread, the filter fits seamlessly into most passenger car engine bays without requiring modifications or adapters.
• Easy Installation: The screw‑on design allows for quick and tool‑free installation. A simple twist secures the filter in place, making maintenance hassle‑free for mechanics and DIY enthusiasts alike.

Compatibility

The MANN‑FILTER Oil Filter W 940/3 is engineered to fit a wide range of passenger car models. Its universal thread size and compact dimensions make it suitable for:

• Front‑wheel drive vehicles with standard oil filter housings.
• Rear‑wheel drive cars that require a 3/4‑16 UNF threaded filter.
• Automobiles equipped with turbocharged engines, where precise filtration is critical to maintain boost pressure and engine longevity.

Performance Benefits

Choosing the MANN‑FILTER Oil Filter W 940/3 offers tangible advantages for vehicle owners:

• Engine Protection: By trapping contaminants, the filter prevents abrasive particles from reaching critical engine components such as bearings and pistons.
• Improved Fuel Efficiency: Clean oil reduces friction, allowing the engine to operate more efficiently and potentially improving miles per gallon.
• Extended Filter Life: The dual anti‑return valves reduce pressure fluctuations that can degrade filter media prematurely, extending the interval between oil changes.
• Consistent Oil Flow: The design ensures a steady flow rate even under high engine loads, maintaining optimal lubrication during acceleration and heavy-duty driving.

Installation Guide

1. Preparation: Warm the engine to operating temperature to ensure oil viscosity is at its normal level. This helps prevent air pockets during installation.
2. Removal of Old Filter: Use a filter wrench or hand tool to unscrew the existing filter. Allow any residual oil to drain before proceeding.
3. Inspection: Check the filter housing for damage, debris, or corrosion that could affect seal integrity.
4. Installation: Align the new MANN‑FILTER Oil Filter W 940/3 with the threaded opening. Hand‑tighten until snug, then give an additional half turn to ensure a secure fit without overtightening.
5. Check for Leaks: After starting the engine, observe the filter area for any oil leakage. Tighten further if necessary.

Maintenance Tips

• Replace the filter at every scheduled oil change to maintain optimal filtration performance.
• Avoid using incompatible filters that lack dual anti‑return valves, as they may compromise engine protection.
• Inspect the filter housing for cracks or wear before each replacement; a damaged housing can lead to leaks and reduced seal effectiveness.
