The Best Air Induction System On The Market!

AEM has pioneered the Cold Air Induction System (CAIS) for sport compacts. Their induction systems create more power than any other system. They relocate the filter outside of the engine compartment for a cooler intake charge. Every AEM air induction system is individually tuned in length and diameter, and features the highest standards of construction - AEM even guarantee's them for the life of your vehicle. Every AEM system is either C.A.R.B. exempt or pending C.A.R.B. exemption.

CAIS Key Features:

  • Outperform every comparable intake system on the market.
  • Utilizes a complete hardware kit with soft mounts for a guaranteed perfect fit.
  • Available powdercoated in Blue, Red, Silver and a unique maintenance-free Polished finish.
  • One-piece, four-layer, cotton-gauze AEM air filter eases installation and features an exclusive air horn design that improves performance.
  • Comprehensive installation instructions, AEM decals and license plate frame included.
  • Manufactured and Assembled in the USA.
  • Limited lifetime warranty.

Note: Short Ram Induction Systems Key Features are the same as the CAIS except it does not relocate filter outside of vehicle.
