The K&N 33-2018 is a washable, reusable panel air filter built on K&N's oiled cotton-gauze high-flow design. It is sized for the factory airbox on 2.5L and 4.0L fuel-injected Jeep Cherokee, Comanche, and Wagoneer models. The manufacturer's engineering goal is to raise airflow while keeping filtration high enough to protect engine longevity, and it rates the filter at up to 99% overall efficiency. Compared with a disposable paper element, this filter can be cleaned and re-oiled instead of replaced at every service, which makes its higher price a long-term value for a Jeep XJ owner who wants a durable K&N air filter upgrade. The manufacturer backs it with a No-Hassle Lifetime Limited warranty.
