Introducing the AMS Performance Subaru EJ WRX\/STI Intake Manifold. The manifold was designed with performance and big HP custom setups in mind. With the level of builds this manifold will be used in, there will be some customizing required. Get yours today!\u003c\/p\u003e\n\u003cp\u003eThe AMS Subaru Intake Manifold was designed to outperform the competition. We referenced many modern design examples and engineering studies to bring you the best intake manifold available for the Subaru EJ20 and EJ25 WRX \u0026amp; STI. After extensive testing we ended up with a manifold that makes more power than anything else currently available on the market!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEngineered To Be The Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor the Subaru EJ Intake Manifold the plan was simple, take our years of engineering experience and design the best intake manifold available. Designed, prototyped, and tested in house by our team of Engineers, the AMS Subaru EJ Intake Manifold was created to be the best unit available on the market. By casting this manifold it is not only stronger, but it allowed us to optimize the power output by giving us the freedom to sculpt the interior geometry for maximum efficiency and airflow.\u003c\/p\u003e\n\u003cp\u003eBy utilizing Solidworks© \u0026amp; CFD (computational fluid dynamics) software we started with an extremely large plenum size of 4.5L for the ultimate top-end power. We also designed CNC machined bellhorns which act as internal velocity stacks and allow for a broad power curve and high RPM horsepower capabilities. This allowed us to optimize massive 2.5? tapered runners and matched cylinder port angles to minimize turbulence and maximize power output. The 13? length of the runners allow for a smooth taper in cross section reduction, giving the AMS Subaru EJ Intake Manifold exceptional flow.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUnmatched power gains and excellent response\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis AMS Subaru EJ Intake Manifold offers more than just top end power. This manifold gives you an amazingly wide power-band with a huge jump in power whenever you are in boost. This equates to greatly improved lap times on the road course and the confidence to leave any opponent in your dust when on the drag strip!\u003c\/p\u003e\n\u003cp\u003eBe the guy to beat, order your AMS Subaru EJ WRX \/ STI Intake Manifold now!\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDue to the large variety of rotated turbo kits on the market, we cannot guarantee fitment with every brand.
