The K&N 57-2585 is a complete cold-air intake system for the 2.0L four-cylinder Ford Fusion. A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and it draws air from outside the engine bay. The tube is paired with an oversized filter, and these systems are paired with a washable, reusable High-Flow Air Filter™ featuring oiled cotton filter media.
The case for paying more than a basic drop-in filter rests on repeatability and warranty. The manufacturer states the kit is guaranteed to increase horsepower and torque, and its dyno listing shows gains of +10.05 hp and +9.6 lb-ft. Because the oiled cotton element can be cleaned and re-oiled rather than thrown away, the filter cost is spread over years of use. The manufacturer also backs the kit with a No-Hassle Lifetime Limited warranty.
Check year coverage before you buy. The manufacturer's listing for this kit shows Ford Fusion L4-2.0L fuel-injected applications from 2013-2016, but the product title references 2013-2015, so confirm your exact model year with the manufacturer. Searches for this kit typically include terms like 2013 2014 2015 Fusion 2.0L cold air intake, roto-molded HDPE intake tube, and washable oiled cotton air filter.
The manufacturer describes the High-Flow filter as washable and reusable. It recommends its Filter Care service kit for cleaning and re-oiling the oiled cotton media.

Mounting hardware is included with the kit, per the manufacturer, so you should not need to source separate brackets. Plan to clean the filter with K&N's recommended care kit and re-oil it before the first install, as the filter ships ready to use but must be maintained over time. The installation time and difficulty level were not confirmed in manufacturer sources during research, so review the included instructions for tube routing and clearance around the engine bay before you start.
