Product Description

The K&N 33-5081 is a direct-fit high-flow replacement air filter engineered for the 2018-2022 Hyundai Accent and 2018-2023 Kia Rio, both sharing the same Gamma II 1.6L naturally aspirated four-cylinder engine and common airbox architecture. It replaces the factory paper element with a layered oiled cotton gauze design that flows significantly more air, supporting improved throttle response and engine efficiency across all trim levels on both front-wheel drive platforms.

Installation is a straightforward drop-in swap into the existing factory airbox with no cutting, drilling, or adapters required. Unlike disposable filters, the 33-5081 is fully washable and reusable using K&N's Recharger cleaning kit, making it a permanent, cost-effective upgrade backed by K&N's 10-Year/Million Mile Limited Warranty.
