Product Description

The K&N 57-2583 Performance Air Intake System is designed to boost horsepower and torque for the 2011-2014 Ford F-150 equipped with the 3.5L EcoBoost V6 engine. By replacing the restrictive factory air box and tubing, this system allows for improved airflow, resulting in enhanced throttle response and engine efficiency. The oversized oiled cotton filter provides excellent filtration and can last up to 100,000 miles before cleaning is required under normal driving conditions.

Installation is straightforward and requires basic hand tools. The intake mounts directly to factory locations and utilizes the stock MAF sensor and crankcase vent connections, making it a true plug-and-play upgrade. Its durable heat shield helps isolate the filter from engine bay heat, ensuring cooler, denser air reaches the turbos for maximum performance gains.

This system delivers an estimated gain of 11 horsepower and 14 lb-ft of torque, all while maintaining emissions compliance under CARB Executive Order D-269-48. Fitment is confirmed for model years 2011-2014 with the 3.5L EcoBoost engine. Fitment beyond 2014 remains unconfirmed at time of listing.
