Product Description

The AEM 25-104BK High Volume Fuel Rail is a performance upgrade designed for **1990-2001 Honda Accord and Prelude 4-cylinder engines**. The large 1/2-inch bore ensures optimal fuel flow for engines with upgraded injectors and supports high-output performance builds. Backpressure pulses are minimized, providing smoother and more consistent fuel delivery under heavy load.

CNC-machined from billet aluminum with a black anodized finish, the 25-104BK is durable and corrosion-resistant. Pre-tapped ends accommodate -6 AN or 9/16"x18 fittings for custom fuel line setups, while the 1/8" NPT port allows integration of a nitrous or fuel pressure gauge. Installation is straightforward using the included hardware and injector O-rings, making this fuel rail a plug-and-play solution for upgraded Honda 4-cyl engines.
