The K&N 69-9900TS is a performance air intake system for the 2017 to 2022 Alfa Romeo Giulia and Stelvio, designed to replace the factory intake tract and filter assembly. Swapping the stock airbox for a performance intake is a common way for owners to pursue a more direct airflow path to the engine, and K&N's reusable filter element is built to be cleaned and re-oiled rather than thrown away. Specific output gains, filter media details, and component dimensions for this kit should be confirmed against the manufacturer's documentation before purchase, since those figures are not included here. Buyers comparing this kit with a cheaper universal intake should check that the part number matches their exact model year and engine before ordering. Searches for 2017-2022 Giulia performance intake, Stelvio cold air intake upgrade, and K&N 69-9900TS fitment will lead to this listing.
