As 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 intake system. Using Koso’s 34mm Throttle Body in conjunction with Koso’s 30.5 to 34mm Intake Manifold (DP623001) will give a better air/fuel mixture for a quicker throttle response.
