    Evo X CAI System

    A cold air intake system relocates the filter outside of the engine compartment to deliver cool air inlet temperatures. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque. But that's only part of the power equation. Every AEM cold air induction system features high standards of construction and we are so confident in their fit and performance that we guarantee them for the life of your vehicle.

    Tuning the inlet pipe in length and diameter to match the engine's resonance helps move more air to the cylinders (think of your engine as a big air pump), and this tuning allows us to deliver large power gains. We also monitor fuel trim correction factors and all OBDII sensors during product development to eliminate leaning the engine out and/or throwing a check engine light.

    Features

    • Non-Woven Synthetic Air Filter
    • Gunmetal Gray Finish
    • Steel Connector Clamps

    Benefits

    • Increased horsepower
    • Tuned and dyno-tested to improve acceleration and engine sound

    • Air filter lasts up to 100,000 miles before cleaning is required (depending on driving conditions)
    • Washable and reusable oil-free filter media

    Applications

    AEM INTAKE

    Amazing looking,sounding and performing intake...glad i was able to get one from MAPERFORMANCE...no brainer for anyone still deciding whether to buy.

    Low Profile Power

    I was looking for an intake upgrade with a proper airbox to utilize the OEM intake scoop and pull in cool air. This one fit the bill. It comes with a dry filter that with no oils to foul up your MAF. Torque increase is considerable in the 3,000 to 5,000 RPM range! Which is a useful for the street. I was not expecting that much difference in the mid-range. Of course, more HP at the top of the RPM range as well.

    Tip: The installation instructions skipped the step of attaching the metal MAF tube to the airbox via a bushing on the underside. Keep a mental note to securing the metal MAF tube to the airbox BEFORE installing the airbox or you won’t be able to reach it once the airbox is in. If you don’t secure the tube, the tube will shift back over time and your bypass/blowoff valve will make contact with the strut bar and rattle.

    Great product

    Very good product, easy to install and can definitely hear the intake more over the stock. I would recommend this product. Bought this for my 2015 Evo X MR.
