Enhance your vehicle's performance with the K&N Engineering Typhoon Cold Air Intake System designed specifically for 2011-2014 Hyundai Sonata and Kia Optima models equipped with a 2.0L turbocharged L4 engine. This system features a mandrel-bent aluminum intake tube that optimizes airflow for increased horsepower and torque, ensuring your vehicle responds more dynamically on the road. The oversized, conical High-Flow Air Filter utilizes oiled cotton filter media, allowing for up to 100,000 miles of maintenance-free operation under normal highway conditions, reducing the need for frequent filter changes. A custom heat shield or air box is included to protect intake air from the high temperatures generated within the engine bay, helping to maintain optimal performance and efficiency. The entire installation process is straightforward and can typically be completed in less than 90 minutes, making it an accessible upgrade for both experienced enthusiasts and DIY installers. This intake system is compliant with EPA standards and carries the CARB Executive Order number D-269-56, although some versions may not be legal for sale or use on pollution-controlled vehicles in California. Backed by K&N's No-Hassle Lifetime Limited Warranty, this intake system offers a reliable, long-term solution for improving your vehicle*s power output and overall driving experience.
