Koso Throttle Body – Honda Grom & Monkey

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 (DY623013) in conjunction with Koso’s 30.5 to 34mm Intake Manifold will give a better air/fuel mixture for a quicker throttle response.
