Honda Civic AEM Cold Air Intake System - 21-401

Brand:
AEM


Details:
Cold Air Intakes
AEM pioneered the Cold Air induction system for sport compact cars in 1994.

A Cold Air intake system relocates the filter outside of the engine compartment to deliver the coolest air inlet temperatures possible. 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. 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 the maximum power gains throughout the entire RPM range. AEM also monitor fuel trim correction factors and all OBDII sensors during R&D to eliminate leaning the engine out and/or throwing a check engine light.

AEM Cold Air systems are dyno-proven and tested against the competition with the goal of creating more useable power than any other system of their kind. Every AEM Cold Air induction system features the highest standards of construction and we are so confident in their fit and performance that we guarantee them for the life of your vehicle. All AEM Cold Air systems include a lifetime DRYFLOW Synthetic air filter and come with a limited lifetime warranty.

  • Installation:
    The majority of AEM air intake system designs mount to a vehicle in two locations. One mounting location is to the engine at the throttle body and the "cold" or filter end of the inlet pipe mounts to the body of the car. The movement of the engine on the engine mounts allows it to rock inside the engine bay, so we compensate for engine motion by using a soft mount that provides a flexible link for the inlet pipe between the engine and the body of the car. If you do not install the soft mount properly the inlet tube may break at the bracket weld and void the warranty on the intake system. Our instructions provide a detailed diagram of proper installation of the soft mount

    Do NOT completely tighten the fittings and connections down for your AEM Air Induction System until the end of the installation. Although each system is precision engineered and fits exactly the same way on each application, it is sometimes necessary to maneuver the system to its mounting points during the installation process. Tightening all of the clamps and brackets as you go will make this procedure difficult, so you should make them snug enough to hold the position of the intake system and only tighten all fittings and connections once everything is installed and the position of the system is properly aligned.
