Vortex Mini ROK kart engine intake plenum for the airbox. Manufactured from a single piece of plastic in red, and designed to press into the front of the airbox through the main intake slot.
This intake plenum component also should be fitted with the plastic dust cover shield, available separately or as part of the Mini ROK Airbox kit. Without this component, significant dust and debris will enter the airbox and the engine, as the Mini ROK does not utilize an air filter per the ROK Cup USA regulations.
