DeutschTuning proudly offers VRSF aluminum chargepipe upgrade for your M3/M4 which replaces the weak plastic chargepipes that are prone to failing at and above OEM boost levels. Our aluminum chargepipes feature CNC billet aluminum flanges and they are finished in powder coated wrinkle black. Two plugged water injection bungs are included for those who are currently using water injection or interested in using water injection in the future. We include everything required to replace your OEM hot side chargepipes. Please note that we now offer an optional cold side upgrade kit that connects the intercooler to the intake manifold and it includes the retaining clip and o-ring necessary for an easy install.
