Product Description

The AEM 21-678C Cold Air Intake System is engineered exclusively for the Mitsubishi Lancer Evolution X (Evo X) equipped with the 2.0 L turbocharged engine, covering model years 2008-2016. Dyno-tested to deliver approximately 17 HP gain at 4,100 RPM, this system replaces the restrictive stock intake with a high-flow aluminum tube and specialized airbox to bring in cooler, denser air for enhanced engine response.

The oversized, oil-free Dryflow filter is designed for longevity and performance - washable and reusable, with up to 100,000 mile service intervals depending on driving conditions. The intake system is built to maintain compatibility with factory emissions controls, includes the required airbox for temperature management, and carries a CARB EO (D-670-26) for legality across all U.S. states. AEM's limited lifetime warranty backs the product. Fitment is confirmed through 2016; coverage for 2017 and beyond is unconfirmed at this time.
