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.

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.

All of the design features of the 2011, 2012, 2013, and 2014 Hyndai Sonata and Kia Optima 2.4L AEM cold air intake system are tuned to improve horsepower and torque delivery in a usable RPM range compared to the factory air filter box system. On the dyno, a 2014 Kia Optima 2.4L Theta GDI equipped with AEM CAI 21-736C made an estimated additional 7.0 horsepower and a very beneficial 10 lb-ft more torque at a commonly used 3,900 RPM . In addition to increasing horsepower, lowering air intake tract restriction and increasing airflow will improve acceleration, drivability, and give your Sonata or Optima a sportier engine sound.

The 2011, 2012, 2013, and 2014 Hyndai Sonata and Kia Optima 2.4L AEM cold air intake system is an excellent performance upgrade for your stylish KDM sedan. This is a complete Hyndai Sonata or Kia Optima cold air intake system including all the necessary hardware and step by step installation instructions. To provide peace of mind, AEM Induction Systems stands behind its products with a Lifetime Limited Warranty.
