Compared to the OEM Charge Pipes, the WAGNER system has a larger flow diameter and no innumerable internal cross-sectional changes, as found in the OEM product. This results in 40% less back pressure, which relieves the turbocharger and, at the same time, ensures better response behavior (see Flow Bench graphic below). 

The WAGNER Charge Pipes are made entirely of aluminum and, unlike the OEM product, do not burst under load (high pressure and due to age). The unique structure powder coating serves not only to protect against corrosion but also for OEM optics.

The kit comes with the following:

(2) aluminum charge pipe (powder-coated black)
(2) silicone adapter (black)
(4) hose clamps stainless steel
(1) mounting material
