The modular adapter, T-piece is designed for YETI injectors. It allows the connection of individual injectors using a gas hose through 360º rotatable supply nozzles with a diameter of Ø 12. The T-piece can be rotated around the injector axis. This solution eliminates gas hose stress caused by variable temperature and engine vibrations during vehicle operation. The component is made of high-quality composite material, resistant to variable temperature and mechanical damage.
