K&N

K&N Engineering has been making performance air filtration products since 1969 when Ken Johnson and Norm McDonald developed the first cotton gauze oil-charged filter in a Reno, Nevada garage. The brand’s core technology has remained consistent for over five decades — a layered oiled cotton media that flows more air than paper filters while stopping particles before they reach the engine. For Jeep Wrangler owners, K&N offers both replacement drop-in air filters and full cold air intake systems compatible with the 3.6L Pentastar and 2.0L turbo engines found in JK and JL models. Their intake systems are designed to increase airflow volume and are backed by a million-mile limited warranty. The filters are washable and reusable, making them a long-term replacement for disposable paper elements. For Wrangler owners focused on engine protection and modest performance gains, K&N is a well-established solution. Browse the full K&N lineup at BlackDogMods.
