Studies have shown Flow rates of up to 80% more Air and Better Dirt Filtration with Foam Filter than the conventional cotton filter.

The Secret Weapon Air Filter's main feature is an CAD Designed and Flow benched Tested Velocity Stack, which greatly increases airflow ,airspeed and air mass into the engine, therefore increasing engine performance. Another one of the Secret Weapon Air Filter's great features are the capability to be disassembled to be cleaned and then re-assembled after cleanings of the foam filtering element.
