Original MANN-FILTER Air Filter C 31 143 – For Passenger Cars

MANN‑FILTER Air Filter C 31 143

The MANN‑FILTER Air Filter C 31 143 is a high‑performance, OEM‑grade air filter designed specifically for passenger cars. It delivers superior filtration efficiency while maintaining optimal airflow, ensuring that the engine receives clean, dry air for maximum power and fuel economy.

Key Features

• Premium Filtration Media: Constructed with a multi‑layer filter medium that captures fine particulates down to 0.5 µm, protecting the combustion chamber and prolonging engine life.
• Optimized Airflow: Engineered to provide low resistance, allowing the engine to breathe freely even under high load conditions.
• Durable Construction: The filter housing is made from reinforced polypropylene, resistant to abrasion and chemical degradation.
• Easy Installation: Fits standard MANN‑FILTER mounting brackets; no modification required. The filter can be installed in under five minutes with a simple snap‑in mechanism.
• Long Service Life: Designed for extended use, the C 31 143 maintains performance for up to 30,000 km (or as recommended by the vehicle manufacturer) before replacement is advised.

Compatibility

The filter is engineered for a wide range of passenger vehicles. It matches OEM specifications for models such as:

• BMW 5 Series (E60/E61)
• BMW 6 Series (E63/E64)
• Alpina variants of the 5 and 6 series
• Other passenger cars with a standard air intake system that accepts a C 31 143 sized filter.

Because it is an OEM‑approved part, you can trust that it will fit seamlessly into your vehicle’s existing airflow architecture without compromising performance or emissions compliance.

Performance Benefits

• Enhanced Engine Efficiency: By delivering cleaner air, the filter reduces combustion chamber fouling and improves fuel atomization, leading to smoother acceleration and better throttle response.
• Improved Fuel Economy: Lower airflow resistance translates into reduced engine load, which can result in a measurable increase in miles per gallon (MPG).
• Reduced Emissions: Cleaner intake air helps the catalytic converter operate more effectively, lowering harmful exhaust emissions.
• Extended Engine Life: Protects critical engine components from dust and debris, decreasing wear on pistons, valves, and bearings.

Installation Guide

1. Locate the existing air filter housing in your vehicle’s intake system.
2. Remove the old filter by releasing the snap‑lock or unclipping the retaining clips.
3. Clean any residual dust from the housing with a dry cloth to ensure proper sealing.
4. Insert the new C 31 143 filter, aligning it with the mounting tabs.
5. Secure the filter by snapping it into place or tightening the retaining clips until fully seated.
6. Verify that the filter is flush and there are no gaps between the housing and the filter edges.

Maintenance Tips

• Inspect the filter every 10,000 km or after driving in dusty conditions; replace if it appears clogged.
• Avoid using compressed air to clean the filter, as this can damage the media layers.
• Store unused filters in a dry, cool environment to preserve their integrity.
