Product Description

The K&N 33-2456 is a high-flow, washable drop-in panel air filter covering the Y62-platform full-size SUV lineup from Infiniti and Nissan - including the QX56 (2011-2013), QX80 (2014-2024), Armada (2017-2024), and international Patrol Y62 (4.0L V6 and 5.6L V8, 2010-2024). All supported models share the same body-on-frame architecture and airbox configuration across both V6 and V8 engine options. 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 - producing improved throttle response and measurable horsepower gains.

Installation is a simple drop-in - remove the stock filter and place the K&N directly into the factory airbox with no tools, adapters, or modifications needed. With a service interval of once every 75,000 miles and K&N's 10-Year/Million Mile Warranty, the 33-2456 is a long-term, cost-effective performance upgrade for QX56, QX80, Armada, and Patrol owners across all trim levels and drivetrains. Note: the 2025+ Armada uses a new 3.5L V6 Twin-Turbo engine - use K&N 33-5149 for that application.
