The new NEUSPEED rising-rate fuel pressure regulator is perfect for all aftermarket supercharged and turbocharged engines that use the VW and Audi fuel rails with Bosch fuel pressure regulators. This precision rising rate regulator will give you increased fuel pressure at the higher rev limits where you need it, so that in many cases you will not need to change injectors. Precision CNC machined of 6061 T6 billet aluminum. Very easy installation. Maximum pressure of 70-80 psi. Not needed for 1.8T and 2.7T cars.
This Neuspeed exhaust for my Jetta is incredible! Now my car sound so good and it is not too loud.
