More Info:
The AEM 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 no company on the market can tune an inlet as well as AEM. We 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’s Cold Air systems are dyno-proven and tested against the competition to create 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 AEM 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.
