These genuine, carbon fibre, vents have been specially designed for Gen 3 Hayabusas that are running our TTS supercharger package. They allow air that has passed through the intercooler to flow away from the bike. The vents come with a template, showing exactly where to install them on the plastic front section of the fuel tank. Some cutting and bonding is required.
 
Although designed for supercharged Hayabusas, these vents could also be installed to a stock Gen 3 model, for purely aesthetic reasons.
