AEM High Volume Fuel Rail Black - Select Acura/Honda/Mitsubishi 1990-2006 (25-100BK)

Fits select 1990-2006 Acura, Honda, and Mitsubishi models, including Integra, Civic, Accord, Prelude, S2000, and Lancer Evolution.

The AEM High Volume fuel rail is engineered for high-performance applications where consistent fuel delivery is critical. Featuring a massive 1/2-inch internal bore, this rail supports fuel flow for setups reaching up to 1,000 horsepower. The increased volume significantly dampens backpressure pulses created by larger fuel injectors, ensuring stable pressure at the injector seat even in high-demand scenarios. This rail is CNC-machined from 6061-T6 billet aluminum and finished with a durable black anodizing and laser engraving for a professional, corrosion-resistant finish.

Installation is straightforward as it is designed to work with the factory fuel line using the included custom fitting. For those running upgraded fuel systems, the rail ends are pre-tapped to accept -6 AN or 9/16"x18 fittings. An additional 1/8 NPT port is integrated for easy installation of a fuel pressure gauge or a nitrous fuel pick-up.
