This is the ultimate intake system for your Evo X. This intake system was deisgned from the ground up to enhance your Evo X's 4B11 MIVEC power making abilities. AEM designed this intake to include a fully enclosed airbox which houses a 3x5" DryFlow performance filter. This system utilizes the factory air duct to take advantage of the coolest air flow available. The airbox is made of cross-linked polyethylene and is attached to an aluminum CNC machined MAF adapter. The intake system feeds the Evo X's turbo through a high flow turbo inlet constructed of ultra strong EPDM rubber. This system replaces all of the most critical components of the factory intake system with high quality, well-engineering pieces that not only look great, but make power! In AEM's tests, this intake added 16.6hp and 17tq to the Evo X by way of 54% more airflow than the stock intake provides!
