VTT is proud to offer the very best charge pipe solution for the BMW E Series N54/55 platforms. This system completely does away with the restrictive, and multi-connection stock charge pipe system, and replaces it with a single 6-ply, Heat Resistant, Wire reinforced silicone charge pipe rated at over 200 psi.
These were manufactured to fit TIGHT on purpose. Be careful when installing, do not try to force them on crooked as this can create burrs on either adapter and make proper fitment not possible until the burrs are cleaned up. They fit fine IF they are installed perfectly flush.
