Product Description

The K&N 33-2411 is a high-flow, washable drop-in panel air filter engineered as a direct replacement for the factory air filter across the 2008-2014 Cadillac CTS (2.8L, 3.0L, and 3.6L V6) and the 2009-2015 Cadillac CTS-V (6.2L supercharged V8), covering all available body styles including the Sedan, Coupe, and Sport Wagon. Built with multiple layers of precision-oiled cotton gauze between aluminum wire mesh screens, it flows significantly more air than the restrictive OEM paper filter while maintaining up to 99% filtration efficiency - delivering improved throttle response and measurable horsepower gains across all supported engine configurations, from the base V6 to the supercharged LSA V8.

Installation is effortless - remove the stock filter and drop 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 33-2411 is a durable, long-term performance upgrade for CTS and CTS-V owners seeking more airflow without changing OEM fitment or risking warranty coverage.
