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. 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 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.

  • Guaranteed for life
  • 50-state legal or pending legality - Excluding intake systems that are designated as Off-Road Use Only.
  • Manufactured and assembled in the USA
  • Engineered to produce maximum horsepower and torque
  • AEMs lifetime DRYFLOW Synthetic air filter is up to 99.52% efficient in FINE DUST testing, filters dirt as small as one micron, and never needs filter oil!
