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 28mm Throttle Body in conjunction with this 23-29mm Intake Manifold (DP640000) will give a better air/fuel mixture for a quicker throttle response.*Please note: Compatible with 2022 and newer Honda Grom and Monkey 125.
