The Aeromotive 14182 Top Feed Fuel Rail Kit is a high-performance billet aluminum fuel delivery upgrade engineered specifically for the 2002-2014 Subaru WRX and 2007-2014 Subaru STI. Designed for enthusiasts and tuners pushing beyond factory power limits, this kit replaces the restrictive OEM side-feed injector setup with a true top-feed configuration - unlocking compatibility with a vastly wider selection of high-flow injectors. Whether you're running a built motor, a large turbo, or simply want rock-solid fuel delivery on a modified EJ-series engine, this is the definitive fuel rail solution.
Key Features & Benefits
-
Top-Feed Conversion - Converts the factory Subaru side-feed injector layout to a top-feed design, enabling the use of virtually any aftermarket top-feed injector (550cc, 1000cc, 1650cc, and beyond) for serious power builds.
-
Billet 6061-T6 Aluminum Construction - CNC-machined from aerospace-grade billet aluminum for maximum strength, corrosion resistantce, and a precise fit that OEM and cast alternatives simply can't match.
-
Black Anodized Finish - Hard anodized black finish provides long-lasting protection against fuel, heat, and corrosion while delivering a clean, aggressive appearance under the hood.
-
High-Flow Internal Passages - Aeromotive's engineered internal flow geometry minimizes pressure drop across all four injector ports, ensuring consistent fuel delivery at high demand - critical for boosted and high-horsepower applications.
-
Direct Bolt-On Fitment - Precision-machined to factory mounting points on EJ-series engines; no cutting, drilling, or fabrication required for proper installation.
-
AN Inlet/Outlet Ports - Features industry-standard AN fittings for easy integration with Aeromotive fuel systems, braided lines, and aftermarket fuel system components.
-
Supports Extreme Power Levels - Engineered to flow enough fuel for builds well beyond 600+ WHP when paired with appropriate injectors, fuel pump, and regulator.
-
Complete Kit - Includes all necessary hardware and O-rings for a straightforward installation without sourcing additional components.
