The K&N 63-2586 is an AirCharger-series cold-air intake for the 1.6L four-cylinder EcoBoost in the Ford Fusion. The manufacturer's catalog lists it for 2013–2015 Fusion L4-1.6L models. Its roto-molded HDPE tube pairs with a washable, reusable High-Flow filter using oiled cotton media. The manufacturer also reports an estimated 5.41 hp gain on a 2013 Fusion 1.6L EcoBoost in dyno testing. Compared with a filter-only swap, the tube and custom heat shield help protect intake air from engine-bay heat. The manufacturer adds that reduced restriction should help the turbo spool up more quickly. Set expectations, though: user forums note that aftermarket intake gains can be negligible without other modifications.
Fitment details vary across listings, so confirm your model year before ordering. The manufacturer states the kit is not legal for sale or use in California. The kit carries a No-Hassle Lifetime Limited warranty, and mounting hardware is included. Owners searching for a 2013 Fusion 1.6 EcoBoost cold air intake, a turbo-safe intake, or a K&N 63-2586 install guide will want to check the specs below and the install notes before buying.
The manufacturer lists the kit for the Fusion L4-1.6L in 2013–2015 model years. Some listings show only 2013–2014, so confirm your model year and engine with the manufacturer before ordering.
No. The manufacturer states it is not legal for sale or use in California, including on any pollution-controlled motor vehicle.
The filter is washable and reusable. Confirm the cleaning and service interval with the manufacturer, since sources give differing mileage figures.
Owners on user forums report that Ford has issued guidance calling for high-filtration air filters on these EcoBoost engines, and some believe aftermarket filter changes could affect warranty claims if the turbo is damaged. Check with the manufacturer and your dealer before installing.
The manufacturer describes a typical installation of about an hour. Its general intake install guide lists a ratchet and extension, 14mm and 10mm sockets, an Allen key, flat and Phillips screwdrivers, a 10mm wrench, and pliers. The guide starts by disconnecting the negative battery cable, then unplugging the mass airflow sensor and detaching the EVAP and crankcase vent lines. Next, loosen the clamps on the stock tube, release the upper air filter housing, and remove the bolt securing the housing. The guide also has you move the mass airflow sensor into the K&N adapter with its gasket, so handle that connection carefully. Confirm the model-specific instruction sheet from the manufacturer before you start.
