Sixth generation Hyundai 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, however many 2011-2015 Hyundai Sonata and Kia Optima 2.4L owners are looking to add more power with an AEM cold air intake. AEM 50-state street legal air intake 22-685C differs from the alternate AEM cold air intake system available for 2011-2014 Hyundai Sonata & Kia Optima 2.4L models because AEM designers retained the use of the stock air filter box. The 2015 Hyundai Sonata & Kia Optima 2.4L models do not currently have 50-state street legal status, but may become so in the near future. Designing AEM cold air intake, number 22-685C, around the stock air filter box allowed AEM Intake designers to retain all factory connections, including stock emissions control equipment, to create an air intake system. Installation of the AEM 2011-2015 Hyundai Sonata & Kia Optima 2.4L air intake is incredibly easy compared to the alternate AEM cold air intake and only requires minimal tools with a reduced installation time.
The maze of accordion like intake tubing, and noise baffling installed at the factory adds a source of restriction to stock 2011-2015 Hyundai Sonata & Kia Optima 2.4L models. Included in the AEM air intake system for 2011-2015 Hyundai Sonata & Kia Optima 2.4L models is a free-flowing mandrel-bent aluminum intake tube. This new aluminum AEM air intake tube is designed to eliminate the restriction found in the stock air ducting. Restriction isn’t the only trouble with the stock air intake as it also creates turbulence in the incoming air. The mandrel-bent aluminum intake tube used in 22-685C has a smooth and consistent internal surface for reduced airflow turbulence. 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 air intake system.
To complement the engine compartment of 2011-2015 Hyundai Sonata & Kia Optima 2.4L models the AEM intake tube is protected with a durable charcoal gray powder coat finish that will look great for years to come. An added benefit of the AEM mandrel-bent aluminum intake tube is that it will eliminate the stock intake noise baffling system. This will give 2011-2015 Hyundai Sonata & Kia Optima 2.4L models a sportier engine sound. To accompany that sportier engine sound AEM Sonata and Optima air intake 22-685C is tuned to provide more horsepower and torque across the RPM range. Making usable horsepower increases in common RPM ranges is a design goal at AEM as this yields a performance upgrade that can be used even during normal driving situations.
The AEM air intake system 22-685C is an incredibly fast and easy upgrade for 2011-2015 Hyundai Sonata & Kia Optima 2.4L models. By retaining the stock air filter box, installation of air intake 22-685C can be completed with minimal tools and less time than the alternate AEM air intake system for 2011-2015 Hyundai Sonata 2.4L and 2011-2015 Kia Optima 2.4L models. Simple to follow step by step instructions are included and there is no need to make any other modifications to your Korean built car for increased performance. AEM performance air intake 22-685C is street legal in all 50 states for 2011-2014 Hyundai Sonata 2.4L and 2011-2015 Kia Optima 2.4L models making this performance upgrade available in California and other states adopting California emissions standards.
