The K&N 57-2592 is a Series 57 FIPK cold air intake for the 3.5L EcoBoost V6 in 2015-2016 Ford F-150 trucks. The manufacturer builds it around a high-density polyethylene (HDPE) rotationally-molded tube that is meant to increase airflow volume, and it states the pairing provides a guaranteed increase in horsepower and torque. The intake is paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media.
The strongest case for this kit over a cheaper bolt-on is the filter's service life. The manufacturer says the oversized conical element allows you to go up to 100,000 miles between filter services under normal highway driving conditions. Instead of buying a disposable element at every service, you pay once and clean it as needed, which keeps the long-term cost of this 3.5L EcoBoost cold air intake, F-150 upgrade competitive with recurring filter purchases.
The manufacturer lists this kit for 2015-2016 Ford F-150 trucks equipped with the 3.5L EcoBoost V6 (F/I). If you are unsure whether your truck matches that engine and model year, confirm with the manufacturer before ordering.
The manufacturer says the filter can go up to 100,000 miles between services under normal highway driving. The manufacturer also notes that dusty or off-road environments call for more frequent cleaning.
Per the manufacturer's general K&N installation sheets, start by turning off the ignition and disconnecting the negative battery cable before you remove the factory intake parts. After the kit is installed, the manufacturer advises periodically checking all connections for realignment, clearance, and tightness. When you service the filter, follow K&N's sealing procedure for its Filtercharger-style elements each time, since a filter that is not seated correctly may not seal and can allow damage to the engine.
