Mann Filter Engine Air Filter C 22 018 – OE-fit for BMW X1/X2/228i & MINI Cooper, water‑resistant high‑flow

The MANN-FILTER C 22 018 is a direct-fit engine air filter engineered to deliver reliable, high-flow engine air filtration for compatible BMW and MINI models.

This replacement air filter is built to the original equipment profile so it installs easily and seals correctly in BMW X1, X2, 228i and several MINI Cooper, Clubman and Countryman applications. It combines a flame-retardant, water-resistant filter medium with embossed pleats and Mann’s glue-string pleat retention to maintain shape and consistent airflow under varied driving conditions. The result is cleaner intake air, steady air-fuel mixture behavior and protection against particles that can accelerate engine wear.

How does this filter fit my BMW or MINI?

The C 22 018 is manufactured to the OE housing profile and dimensions for direct replacement—no modifications required. That means a snug gasket seal and correct positioning in the airbox, preserving factory airflow and sensor readings.

• OE-form profile for drop-in replacement
• Precision gasket for tight sealing
• Designed to match original airflow characteristics

What filtration features improve engine protection?

The media is engineered for high dirt-holding capacity while resisting water and heat-related deterioration. Embossed pleats keep structural integrity and the glue-string pleat retention reduces pleat deformation under high air pressure, so contaminants are trapped without restricting flow.

• Flame-retardant, water-resistant filter media
• Embossed pleats for mechanical strength
• Glue-String Technology to stabilize pleat spacing

Will this filter affect performance or fuel economy?

Maintaining correct airflow and preventing clogging helps the engine preserve its intended power delivery and combustion balance. The C 22 018 is designed for low flow resistance, which supports stable engine response and consistent mass air flow sensor readings when replaced at recommended intervals.

• Low flow resistance encourages stable airflow
• High dirt separation reduces sensor contamination
• Helps maintain predictable throttle and efficiency characteristics

How durable is the filter under real-world driving?

Materials and construction are chosen for resilience in everyday and damp conditions—whether city stop-and-go driving or highway cruising. The special coating on the media offers added resistance to moisture and particulate loading, while the overall design minimizes pleat bunching during sudden air surges.

• Special coating for moisture and hot-ash resistance
• Pleat retention to prevent deformation at high speeds
• Robust gasket for long-term sealing performance

Who is this for: Drivers and DIY mechanics who own compatible BMW X1, X2, 228i or MINI Cooper/Clubman/Countryman models and want a high-quality, OE-profile replacement air filter. It’s intended for owners who prioritize correct fit, consistent airflow, and reliable particulate protection to help preserve engine components and maintain expected vehicle behavior between service intervals.
