AEM Air Intake Systems are designed to produce massive horsepower and torque gains as well as better engine sound when used as a replacement for the factory airbox and air filter. AEM intake systems are designed, tuned, and dyno-tested to fit specific cars and trucks. These air intakes usually include an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration, and performance while allowing easy oil-free cleaning. Most AEM intake systems use mandrel-bent aluminum intake tubes, powder-coated heat shields, 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.

  • Engineered to add horsepower and reduce restriction compared to OEM air intakes
  • All AEM Air Intakes come with a lifetime DRYFLOW Synthetic air filter with great filtration
  • Lifetime limited warranty
  • Manufactured in the USA
