The KG BOOSTER air box is one of the most successful on the market, specially designed to offer a maximum air flow While respecting the FIA standards in force.
Equipped with Internal filter PO37 sprintIt guarantees an extremely low pressure drop, allowing the engine to breathe fully and to express its potential, both on the boxes with box (Kz) and on the mono-speed categories (OK - OKJ - OKNJ).

Thanks to his Innovative internal design, the KG Booster combines performance, noise reduction, particle control, and Optimization of the airflowWhat makes it a reference for competitors looking for the best of Italian technology kg.
