Description
Original AEM Adjustable Fuel Pressure Regulator for Honda
The AEM adjustable fuel-pressure regulator is engineered to provide precise control of fuel pressure for standard, tuned, turbocharged and supercharged Honda engines. Its adjustable design allows the fuel pressure to be matched correctly to the engine, injectors and fuel-pump setup.
Manufactured from CNC-machined 6061-T6 billet aluminium, this regulator offers excellent strength, durability and resistance to demanding engine-bay conditions. Fuel pressure can be adjusted from approximately 20 PSI up to the maximum capacity of the fuel pump.
Its boost-referenced 1:1 rising-rate design increases fuel pressure by approximately 1 PSI for every 1 PSI of boost, helping maintain consistent fuel delivery on turbocharged and supercharged applications. According to AEM, it can support sufficient fuel flow for engines producing up to 1,000 horsepower when used with a properly designed fuel system.
