The ultimate fix to the X3's oversize, ugly, bulky, and restrictive clutch vent hose. This oversize silicone hose allows for drastically more air flow through the back side of the engine. The factory hose is so large that it restricts any air flow past and retains this heat. The SHORTY from RPM is, as pictured, drastically smaller, smoother flowing, with a larger exit snout. This is a win, win, win, product! If you're running a bed delete then aesthetically, this is a MUST!
