Original MANN-FILTER Air Filter C 34 120 – For Passenger Cars

MANN‑FILTER Air Filter C 34 120

The Original MANN‑FILTER Air Filter C 34 120 is a high‑performance engine air filter designed specifically for passenger cars, with a strong focus on BMW models such as the 5 Series, X3, X4 and X5. It delivers superior protection against dust, dirt, pollen and other contaminants while maintaining optimal airflow to the combustion chamber.

Key Features

• OEM‑specification: The filter is engineered to meet or exceed the original equipment manufacturer (OEM) standards for BMW vehicles, ensuring a perfect fit and reliable performance.
• Advanced Filtration Technology: Utilises a multi‑layer media system that captures particles as small as 0.3 µm, providing excellent protection against fine dust and airborne pollutants.
• High Airflow Capacity: Designed with a low pressure drop to maximise engine breathing, which can improve fuel efficiency and power output.
• Durable Construction: Made from high‑quality synthetic fibers that resist compression and maintain filtration efficiency over extended periods of use.
• Easy Installation: The filter’s dimensions (approximately 343 mm length × 114 mm width × 60 mm height) match the original air box design, allowing for a tool‑free installation in most BMW models.
• Long Service Life: Engineered to stay effective for up to 30,000 km or 12 months under normal driving conditions, depending on environmental factors.

Compatibility Overview

The C 34 120 is specifically tailored for a range of BMW passenger cars. Below are the most common models that use this filter size:

• BMW 5 Series (F10, F11, F18)
• BMW X3 (F25, F26)
• BMW X4 (F26)
• BMW X5 (F15, F85)

It is also compatible with many other passenger cars that share the same air box dimensions and filter mounting system. Always verify the model year and engine type before installation.

Installation Guide

1. Prepare the Vehicle: Park on a level surface, engage the parking brake, and allow the engine to cool if it has been running.
2. Locate the Air Box: Open the hood and locate the air intake box. The filter is usually positioned at the rear of this compartment.
3. Remove the Old Filter: Carefully lift the cover or seal, then slide out the old filter. Dispose of it responsibly.
4. Insert the New Filter: Place the new C 34 120 filter into the air box, ensuring that the airflow direction arrow points correctly (usually towards the engine).
5. Secure the Cover: Replace the cover or seal and tighten any fasteners. Verify that there are no gaps where unfiltered air could enter.
6. Check for Leaks: Start the engine and listen for any unusual noises or airflow leaks around the filter housing.

Maintenance Tips

• Inspect the filter every 10,000 km or after heavy driving conditions (e.g., dusty roads, construction sites).
• Avoid using compressed air to clean the filter; it can damage the media and reduce filtration efficiency.
• If you notice a significant drop in engine performance or an increase in fuel consumption, consider replacing the filter sooner than the recommended interval.

Performance Benefits

By maintaining clean air intake, the MANN‑FILTER Air Filter C 34 120 helps preserve engine longevity and performance. Clean air reduces combustion temperature variations, which can lower wear on pistons, valves, and other internal components. Additionally, a well‑filtered air stream contributes to more consistent throttle response and smoother acceleration.

Environmental Impact

The filter’s high filtration efficiency means fewer particulates are released into the atmosphere, supporting cleaner emissions. Moreover, its durable construction reduces waste by extending service life compared to lower quality filters that require frequent replacement.
