K&N's washable, reusable High-Flow filters use layered, oiled cotton media, and the E-1998 applies that design as a round, straight element that drops into the factory air box. Because it is reusable, it replaces the disposable paper filter that the stock system uses, and the filter is backed by K&N's No-Hassle Lifetime Limited Warranty. The manufacturer positions these filters for added horsepower, but it does not publish a horsepower figure for this part, so treat any gain as a modest, unquantified benefit. Fitment is the first thing to confirm: the manufacturer's page lists the Jeep Compass L4-2.0/2.4L F/I, while Patriot and Caliber year coverage varies across sources, so check the manufacturer's application guide against your VIN before ordering.
The manufacturer's listing names the Jeep Compass with the 2.0L and 2.4L fuel-injected engines. Year and model coverage for the Patriot and Caliber vary between sources, so confirm your exact year and engine against the manufacturer's application guide before ordering.
The cleaning interval depends on driving conditions, and published figures differ between sources. Check the manufacturer's maintenance guidance for your driving pattern rather than relying on a single mileage number.
Per the manufacturer's install sheets for comparable drop-in K&N filters, the swap involves removing the stock element, wiping out dirt from the housing, seating the new filter, pressing its edges to seal, and reinstalling the lid. K&N states that these steps must be followed every time the filter is serviced, or the filter may not seal. The manufacturer's hints also suggest disconnecting the intake tube from the air box lid to make the lid easier to maneuver, and noting that some K&N filters seat into the lid first, so hold the element in place with your fingers while the lid goes back on. Confirm the exact sequence against the instruction sheet packed with your filter.
