Sixth generation Hyndai Sonata as well as third generation Kia Optima models come standard with the 2.4-liter Theta GDI direct injection engine. This new engine makes more horsepower than the standard inline four that it replaces, and nearly as much as the old 2.7L MU V6 engine while being rated at an EPA estimated 35 MPG highway. The Sonata and Optima can be equipped with an available 2.0L Turbocharged engine but this makes for a considerably more expensive car. 2011, 2012, 2013, and 2014 Hyndai Sonata and Kia Optima 2.4L owners looking to add more power without breaking the bank are able to do so with an AEM cold air intake. By reducing air intake tract restriction, and turbulence, AEM is able to increase horsepower, torque, acceleration, and provide better engine sound with the installation of an AEM CAI system.

The standard engine for 2011-2014 Hyundai Sonata models, and the rebadged Kia Optima, is a 2.4L Theta GDI direct injection engine rated at nearly 200 horsepower

At AEM Induction Systems our engineers design our intake systems as a fully integrated component of the vehicle. Improved airflow is only part of the power equation. The 2011-2014 Hyndai Sonata and Kia Optima 2.4L AEM cold air intake system relocates the AEM Dryflow air filter outside of the engine compartment and with the help of a charcoal gray powder coated aluminum air intake tube it is able to provide cooler, denser outside air for more efficient combustion. AEM cold air intake 21-736C comes equipped with a non-oiled AEM Dryflow air filter, number 21-203D, which delivers high airflow, excellent filtration, and exceptional engine protection. The mandrel bent aluminum cold air intake tube and provided AEM badged shield is finished with a durable charcoal gray powder coat finish to provide long lasting good looks.
