The BLOX Racing adjustable fuel pressure regulator (FPR) is an affordable and easy-to-install alternative to those complicated and expensive aftermarket units.

This billet aluminum piece installs on to the factory fuel pressure regulator, turning it into an adjustable unit, allowing users to properly tune the air / fuel ratio. This is ideal for any aftermarket products requiring a bump in fuel pressure. It is designed to work with the factory fuel rail.

Range: 25-60psi 

NOTE: Requires modifications to factory fuel pressure regulator and or fuel rail. Instructions provided.
