Description

ECD-QL Universal Pleated Open Top Qualifying Air Filter – Fits 2.5" Flange


The ECD-QL Universal Qualifying Air Filter is a high-flow, open-top air filter designed specifically for short runs and qualifying sessions where maximum airflow is essential. With no top cap to restrict airflow, this filter delivers uninterrupted air volume directly to the carburetor, making it ideal for racers seeking peak performance in time trials or sprint laps.


This filter is compatible with all 2.5" O.D. velocity stacks and air filter adapters, commonly found in go-karts, mini bikes, and small engine racing applications.


Not recommended for dirt tracks or extended sessions.
The open-top design allows for increased airflow but offers no protection from dust, dirt, or debris. Use only in controlled or clean environments, such as pavement tracks or dyno testing.
