Intake Velocity Stacks for Honda MSX / Grom 125cc.
This upgrade helps to allow to bring the most air possible to the intake with the least amount of turbulence. Together with the snorkel delete, this will improve the performance of the bike in High RPM/High load, give you a better throttle response and improve the sound of the bike.
You should print this, AT LEAST, in quality PETG (ABS or ASA advised).
