The K&N 33-2445 is a washable, reusable high-flow engine air filter for the 5.0L V8 fuel-injected Jaguar XK. Its element uses layered, oiled cotton media that the manufacturer says is designed to raise airflow while still capturing contaminants that wear on an engine. Because the filter is cleaned and re-oiled rather than discarded, it is meant to stay in service for the life of the vehicle, which is the main reason to pay more than a basic disposable filter costs.
The purchase case rests on durability and value over time. The manufacturer backs the element with its No-Hassle Lifetime Limited Warranty and says the design is intended to add horsepower, though no dyno figure was confirmed during research. Each box holds two filters, so you get a spare on hand while one is being cleaned. Search terms that fit this part include K&N 33-2445 high-flow filter, Jaguar XK 5.0L V8 washable air filter, and oiled cotton gauze XK engine air filter upgrade.
