Description
The AEM 25-100BK High Volume Fuel Rail is designed for Acura B18B1, B18C1 and B18C5 engine applications. It provides a larger internal fuel passage and connection options for a supported Integra fuel-system installation.
Design and operation
The CNC-machined billet aluminum rail uses a ½-inch internal bore to provide fuel volume and help damp pressure pulsations associated with injector operation. Its black anodized finish includes laser engraving. A separate ⅛-inch NPT port provides a connection for a suitable pressure gauge or auxiliary fuel takeoff.

Important application notes
Application: Acura B18B1, B18C1 and B18C5 engines. The previous broad multi-vehicle fitment table has been excluded because it conflicts with this engine-specific rail. Rail capacity alone does not establish a safe engine power limit; pump, injectors, regulator and calibration remain separate requirements.
