AEM's Adjustable Fuel Pressure Regulators for Hondas and Acuras are constructed of 6061 T-6 billet aluminum and are capable of supporting enough fuel flow for engines in excess of 1000 horsepower. Only AEM regulators have patented replaceable discharge ports that allow the user to tailor the regulator's output to the output of ANY fuel pump, whether it be the stock unit or a high-flow aftermarket pump. The base of the regulator is tapped to accept the stock hose barb fitting or an AN fitting.
