Fits 2020+ CADILLAC CT5/CT5-V ( 3.0L TT MODELS )
DESCRIPTION:
Keep your Cadillac’s factory intake system while replacing its disposable filter elements with the K&N 33-5105 Drop-In Air Filter. This application covers 2020-2026 CT4-V Blackwing models with the 3.6L twin-turbo V6 and 2020-2026 CT5 Premium Luxury and CT5-V models equipped with the 3.0L twin-turbo V6. Two matching filters are required to complete the vehicle, with each element fitting inside its original airbox. K&N’s High-Flow design supports airflow and engine performance without replacing the intake housings or tubing. Each panel contains four layers of oiled cotton-gauze media designed to capture incoming contaminants. The filter arrives pre-oiled and can be washed for continued service, making maintenance a matter of cleaning and re-oiling rather than purchasing another disposable element. K&N’s dedicated filter-care products remove accumulated dirt and restore the treated media for reuse. For Cadillac owners maintaining a stock intake arrangement, the 33-5105 offers a lasting filtration option.
