This is a velocity stack that was designed for a Honda 4 cylinder engine with fuel injection, primarily for racing use, you will need a mesh cover as there is no air filter attachment. I designed this for a friend who races, the pictures are just a mock up done in pla, I am using PAHT-CF for the actual part and printing this on a P1S with a hardened hot end nozzle and a engineering plate.. The part will need to be attached with a rubber or silicone boot and clamps, it is in no way to be deemed as street legal or an engineered part, I am just a 3D hobbyist who is having fun and maybe someday will make this my side hustle.
