16- Cadillac CTS-V 6.2L Air Filter

The K&N 33-5059 air filter for the 2016–2018 Cadillac CTS-V 6.2L is engineered for serious enthusiasts who demand both raw engine performance and extended service intervals. As a high-flow replacement for GM's GenV LT-series engine platform, this panel-style air filter drops directly into your CTS-V's factory airbox, delivering unrestricted airflow to the supercharged 6.2L powerplant while maintaining proper engine protection. Unlike disposable paper filters, K&N's reusable cotton design means fewer replacements and lower long-term costs—critical advantages for owners pushing their Cadillac's 645 horsepower to the limit on the street or track.

This filter element measures 10.063 x 10.063 inches with a 1.438-inch height, precisely matched to the CTS-V's intake geometry for optimal air velocity and filtration efficiency. The signature red cotton media is treated with K&N's proprietary oil formula, which captures contaminants while offering 50% more airflow than OEM filters—a measurable advantage when every cubic foot per minute matters in forced-induction applications. The reusable construction means you'll simply clean and re-oil it every 50,000 miles rather than replacing it, making it both an environmentally responsible choice and a genuine performance investment that pays dividends over the life of your vehicle.

Cadillac CTS-V owners seeking measurable intake improvements will find this filter particularly effective when combined with other GM GenV LT modifications, including intake manifold work or ECU tuning. Installation requires no special tools—it's a direct bolt-in replacement that takes minutes and delivers noticeable throttle response gains in supercharged applications. This filter is compatible exclusively with 2016–2018 model-year CTS-V vehicles and will not fit earlier or later generations; verify your year and engine code before ordering to ensure proper fitment and warranty coverage.
