The original oil breather set up on N55s can cause issues with carbon build-up inside the engine’s intake system over time. It forms an oily sludge that covers parts of the intake and inlet valves, which reduces airflow and therefore performance and efficiency.
Hence oil catch cans are vital preventative additions to ensure the performance and efficiency of Direct Injection engines doesn’t deteriorate over time.
AIRTEC Motorsport’s solution to developing a catch can kit specifically for the BMW M models utilises the available space to integrate seamlessly within the engine bay.
The can itself features an internal micron filter, baffle and dipstick and detaches to allow easy maintenance. It comes with a comprehensive fitting kit that includes all fixtures and fittings, as well as a detailed installation guide.
