Original MANN-FILTER Fuel Filter WK 1136 – For Passenger Cars

MANN‑FILTER Fuel Filter WK 1136 – The Ultimate Protection for Passenger Cars

The MANN‑FILTER Fuel Filter WK 1136 is engineered to deliver uncompromised protection for the fuel system of modern passenger vehicles. Designed with precision and built using high‑grade materials, this filter guarantees that only clean, contaminant‑free fuel reaches your engine, thereby preserving performance, efficiency, and longevity.

Key Design Features

• Advanced Filtration Technology: The WK 1136 employs a multi‑layer filtration matrix that captures particles as small as 0.5 µm, ensuring the removal of dirt, rust, and other impurities.
• Durable Construction: Constructed from reinforced polypropylene housing, the filter resists cracking and maintains structural integrity under high pressure and temperature conditions typical in passenger cars.
• High Flow Capacity: With a flow rate of up to 250 L/h, it delivers sufficient fuel throughput for both gasoline and diesel engines without compromising filtration efficiency.
• Long‑Lasting Seal: The filter features an integrated O‑ring seal that prevents backflow and ensures airtight operation throughout its service life.
• Easy Installation: Designed with a standard 110 mm diameter, the WK 1136 fits seamlessly into most passenger car fuel lines without the need for custom adapters or modifications.

Compatibility and Applications

The WK 1136 is specifically tailored for passenger cars, offering broad compatibility across a range of models. It is commonly used in:

• Audi A8 series (4E2, 4E8) – both gasoline and diesel variants.
• Other European passenger vehicles that require a 110 mm fuel filter.
• High‑performance engines where precise filtration is critical for optimal combustion.

Its universal design allows it to be swapped into any vehicle that accepts the standard size, making it an ideal choice for mechanics and DIY enthusiasts alike.

Installation Guide

1. Safety First: Disconnect the battery and relieve fuel system pressure before beginning work.
2. Remove Old Filter: Unscrew or unclip the existing filter housing, allowing any residual fuel to drain into a suitable container.
3. Position WK 1136: Align the new filter with the inlet and outlet ports. Ensure that the flow direction arrow on the filter matches the vehicle’s fuel line orientation.
4. Screw or Clip Securely: Tighten the housing until it is snug but not over‑tightened to avoid damaging seals.
5. Re‑pressurize System: Reconnect the battery, then gradually re‑pressurize the fuel system according to manufacturer guidelines.
6. Check for Leaks: Inspect all connections for any signs of leakage. Tighten as necessary.

Performance Benefits

• Engine Protection: By filtering out contaminants, the WK 1136 prevents wear on fuel injectors and pumps, extending their service life.
• Fuel Efficiency: Clean fuel flow promotes optimal combustion, which can translate into better mileage and reduced emissions.
• Reliability: Consistent filtration performance reduces the likelihood of engine misfires or stalling caused by clogged fuel lines.
• Maintenance Simplicity: The filter’s robust construction means it can withstand harsh operating conditions, reducing the frequency of replacements.

Quality Assurance and Standards

The WK 1136 is manufactured under strict quality control protocols that adhere to ISO 9001 standards. Each filter undergoes rigorous testing for:

• Pressure retention at maximum operating pressure.
• Particle filtration efficiency across a range of fuel viscosities.
• Durability under thermal cycling and vibration.

This commitment to quality ensures that every unit delivers reliable performance from the first use onward.
