VRSF Charge Pipe Upgrade - BMW E82/E88/E90/E92 N54/N55
The VRSF Charge Pipe Upgrade replaces the factory chargepipe on N54 and N55 powered 135i and 335i models with a full aluminum piece finished in powder coated black. A CNC billet throttle body flange keeps the factory c-clip retention system in place, giving a tighter seal than the clamp-and-coupler design used by some competing pipes.
Important Compatibility Information
Choose the variant above that matches your engine and blow-off valve setup: N54 with the OEM twin diverter valve setup, N54 with a Tial or Turbosmart aftermarket BOV, N54 with an HKS BOV, or N55 with no BOV flange.

Frequently Asked Questions
Which variant do I need if I have an aftermarket blow-off valve?
Pick the flange that matches your BOV: Tial/Turbosmart or HKS on N54, or the no-flange N55 version if your BOV setup uses a different mount.
Do I need to run methanol injection to use this pipe?
No. The two NPT bungs are plugged from the factory and only need to be opened if you add water or methanol injection later.
Does this keep the factory oil separator or catch can connections?
The pipe includes caps for the intake recirculation ports it replaces; consult the install guide for how your specific catch can or PCV setup connects if you're running one.
