Increase throttle response and decreases turbo lag with the VRSF charge pipe for your 135i/335i/335is. Our aluminum charge pipe features a CNC billet aluminum OEM throttle body flange and is finished in powdercoated black. The VRSF charge pipe retains the OEM c-clip in order to provide a better seal over a conventional clamp/coupler design. This charge pipe is offered with the Tial BOV flange only. Two plugged meth bungs are included for those who are currently using meth or interested in using meth in the future.
