Koso 34mm Throttle Body / Manifold Kit


The throttle body and intake manifold are used to control the amount of air flowing to the engine’s combustion chamber, they are important elements of the admission system. Using our Koso’s 34 mm throttle body in conjunction with our 30.5 to 34mm intake manifold will allow a better air/fuel mixtures for a quicker throttle response.
