Increase throttle response and decreases turbo lag with the VRSF chargepipe for your 135i/335i/335is. Our aluminum chargepipe features a CNC billet aluminum OEM throttle body flange and is finished in powder-coated black. The VRSF chargepipe retains the OEM c-clip in order to provide a better seal over a conventional clamp/coupler design. We also offer the chargepipe with a Tial or HKS bov flange as well as a N55 setup. Two plugged meth bungs are included for those who are currently using meth or interested in using meth in the future.
