5 Bar Fuel Pressure Regulator FPR for 996TT

The OEM fuel pressure regulator is 3.8 Bar (55.86psi). This is the amount of fuel pressure that is maintained in the fuel rail. In high power applications, when the boost pressure and power is increased, a drop in fuel pressure can occur causing a lean condition with the OEM 3.8 Bar regulator. Installing a 5.0 Bar (73.5psi) FPR will eliminate loss in rail pressure while under full acceleration.
