Product Description

The K&N 33-2399 is a high-flow, washable panel air filter built as a direct drop-in replacement for factory air filters across a wide range of Infiniti and Nissan VQ-platform vehicles, including the G35, G37, G25, EX35, EX37, Q40, Q60, QX50, 350Z, and 370Z. Constructed with multiple layers of precision-oiled cotton gauze between aluminum wire mesh, it delivers significantly more airflow than restrictive OEM paper filters while maintaining up to 99% filtration efficiency. The result is noticeably improved throttle response and horsepower without any modification to your stock airbox.

Installation requires no tools or adapters - simply remove your old filter and drop the K&N in. The flexible frame design ensures a proper seal to prevent unfiltered air from entering the engine. With a cleaning interval of just once every 75,000 miles and K&N's 10-Year/Million Mile Warranty backing every unit, the 33-2399 is a reliable, cost-effective performance upgrade for daily drivers and enthusiasts alike.
