AEM's Adjustable Fuel Pressure Regulator for Honda/Acura is constructed of 6061 T-6 billet aluminum and is capable of supporting enough fuel flow for engines in excess of 1000 horsepower. Only AEM regulators have patented replaceable discharge ports, which allows the user to tailor the regulator's output to the output of ANY fuel pump, whether it is the stock unit or a high-flow aftermarket pump.
