Product Description

The K&N 33-5079 is a direct-fit high-flow replacement air filter engineered for the Lexus RX450h and RX450hL (2016-2022) and the Toyota Highlander Hybrid (2016-2019), all sharing the same 3.5L V6 hybrid powertrain platform 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 in both AWD and FWD configurations.

Installation is a straightforward drop-in swap into the existing factory airbox with no cutting, drilling, or adapters required. Unlike disposable filters, the 33-5079 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. Owners of 2020+ Highlander Hybrid or 2023+ Lexus RX models should verify airbox compatibility, as the redesigned platforms use a different fitment.
