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 horesepower 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 we can. 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.

Our 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 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.

AEM Cold Air Intake Systems are designed to produce horsepower and torque gains. They replace the restrictive factory airbox and air filter to give you better performance and better engine sound. AEM cold air intakes relocate the air filter outside the engine compartment so cooler air can be fed into your engine. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber for more horsepower and torque. AEM Cold Air Intakes include an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration, and performance while allowing easy oil-free cleaning. They include a mandrel-bent aluminum intake tube and high quality hardware designed to reduce restriction and reduce intake temperature. The design and components of each intake system vary so consult the installation instructions for more information on the contents of each part number.

Note: This Air Intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.
