Description
Many of you will already be aware that the original plastic charge pipe is a real weak link on the N55, and over the last 6 months we have received many requests after the charge pipes fail. If you take a look at the images above you can see how the coupler becomes brittle leading to cracking, fracture and ultimate failure. Our alloy replacement uses a CNC coupler to ensure this is a permanent solution.
ORIGNAL O-RINGS/SEALS MUST BE RETAINED FOR USE ON THE FORGE HOSES. PLEASE NOTE, HARDPIPES ARE NOW MADE WITH A WATER METH BOSS BUILT IN. THE BOSS CAN BE PLUGGED IF NOT USED, THE PLUG IS SUPPLIED WITHIN THE KIT. This will not fit vehicles with XDrive
