Air intake is 90 degree intake tube with velocity stack. These parts give you two ways of adjusting air intake, you may use just air intake tube or just velocity stack or as suggested both together, depending on your set up air may be reduced or slowed down for best results. Due to limited space this is an answer that solves that problem.

You will need to remove your rear driven clutch assembly and slide this one on simple and easy.

Dr Pulley Sliders at 5gram should be used for bext performance as well as a performance variator that is NOT restricted.
