Our innovative design also includes CNC machined bellhorns that function as internal velocity stacks, resulting in a broad power curve and exceptional high RPM horsepower capabilities. This enabled us to optimize the size and angle of the massive 2.5″ tapered runners and cylinder ports, minimizing turbulence and maximizing power output. The runners measure 13\" in length, ensuring a smooth taper in cross section reduction and providing the AMS Subaru EJ Intake Manifold with outstanding flow.\u003c\/span\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAchieve Unparalleled Performance Improvements and Exceptional Responsiveness\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe AMS Performance Reverse Rotation Intake Manifold for 2002-2014 Subaru WRX and 2004-2021 Subaru STI provides a substantial boost in power throughout the entire power-band, allowing for faster lap times on the road course and an advantage over competitors on the drag strip.
