Product Description

The K&N 33-2448 is a high-flow, washable drop-in panel air filter covering a wide range of Hyundai and Kia models from 2009 through 2017, including the Sonata, Sonata Hybrid, Santa Fe, Azera, Optima, Optima Hybrid, Sorento, and Cadenza. Spanning engine options from the 1.7L L4 through the 3.5L V6, this filter is engineered for multiple platforms sharing the same airbox configuration across both brands. Built with multiple layers of precision-oiled cotton gauze between aluminum wire mesh screens, it delivers significantly more airflow than the restrictive OEM paper filter while maintaining up to 99% filtration efficiency.

Installation is a direct drop-in - remove the stock filter and place the K&N into the factory airbox with no tools or modifications needed. With a service interval of once every 75,000 miles and K&N's 10-Year/Million Mile Warranty, the 33-2448 is a cost-effective, long-term performance upgrade for owners across this broad Hyundai/Kia platform range. Note: for 2013+ Hyundai Santa Fe Sport or 2013+ Kia Sorento (third generation), use K&N 33-2493 instead.
