AEM Cold Air Induction Systems

An AEM Cold Air intake system relocates the air 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 horesepower and torque. But thats only part of the power equation. Tuning the inlet pipe in length and diameter to match the engines resonance helps move more air to the cylinders (think of your engine as a big air pump), and this tuning allows AEM to deliver the maximum power gains throughout the entire RPM range. AEM also monitors fuel trim correction factors and all OBDII sensors during R&D to eliminate leaning the engine out and/or throwing a check engine light.

All AEM Cold Air Intake 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 are either 50-state legal or pending (excluding Off Road and Hybrid systems), include a lifetime DryFlow Synthetic air filter and come with a limited lifetime warranty.
