Turbochargers and VANOS systems utilize pressurized oil lines in order to get lubrication where it is needed most. In the case of the VANOS system, a small leak in the pressure line will cause a pressure drop and the DME will not be able to adjust timing properly resulting in a loss in power.
The HARD Motorsport Oil Cooler Fitting Adaptor Plate allows you to upgrade your oil cooler lines to a flexible braided hose that can be routed in any direction, giving the ability to upgrade or relocate your oil cooler. This kit replaces the oil cooler hard lines with two -10 AN fittings, mounting bracket, O-rings, and adaptor bracket, which is CNC machined stainless steel.
