Description

The K&N 57S-4001 Generation II induction kit replaces the restrictive factory air intake on 2011-2019 Ford Ranger models with a 3.2L L5 Duratorq-TDCi diesel engine, eliminating airflow restrictions for up to 12.74 HP gain at 3844 RPM while improving throttle response and engine sound. It features a washable, reusable air filter and a rotationally molded tube, delivering more air to the engine for real power gains. The kit is designed for quick, bolt-on installation, typically within 60 minutes or less, without requiring any vehicle modifications.
