Product Description
Velocity stacks optimize the flow of drawn-in air to the carburettor. With this airflow optimization benefits throughout the rev range and therefore increases performance. Can be used either completely open for maximum air passage or combined with the included mesh insert.
Fits on PHVA style carburetors found on Tomos A55 mopeds. Will also clamp down onto to any other carburetor with a 35mm diameter like the Arreche
Tech Tip: With this open filter you will need to re-jet the carburetor with a larger main jet. More air will need more fuel.
