Description

Part #: 57S-4001

K&N 57i Generation II Induction Kits are built primarily for European vehicles. They come with K&N's No-Hassle Lifetime Limited Warranty. These intake kits use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter alone. The weakest link in the airflow chain robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER.

K&N's easy to install air intake systems replace the restrictive factory air filter and air intake housing allowing for virtually unrestricted air flow. K&N air intakes come with K&N's No-Hassle Lifetime Limited Warranty.

MIA's 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.
