The AEM High Volume Fuel Rail 25-104BK is engineered to deliver superior fuel flow and pressure consistency for high-performance Honda engines. Designed with a large 1/2-inch internal bore, this rail supports fuel systems powering up to 1000 horsepower, ensuring reliable delivery for both naturally aspirated and forced induction setups. The increased bore capacity dampens backpressure pulses created by larger injectors, providing smoother and more consistent fueling—even with factory injector configurations.
Precision CNC-machined from billet aluminum and finished in a sleek black anodized coating, the 25-104BK offers both durability and corrosion resistance. An integrated 1/8-inch NPT port allows for easy installation of a nitrous feed or fuel pressure gauge, while the included custom fuel line fitting connects directly to factory fuel lines for a hassle-free setup. Each end of the rail is pre-tapped to accept -6 AN or 9/16"x18 fittings, giving tuners flexibility for custom fuel system configurations.
Ideal for 1990–2001 Honda Accord and Prelude models, this fuel rail combines OEM fitment with high-performance engineering. It’s the perfect upgrade for enthusiasts seeking improved fuel flow capacity, precise pressure stability, and professional-grade reliability in their performance builds.
