Part #: 57-2549

Overview

The K&N 01-04 Ford Lightning / F150 Heavy-Duty Performance Intake Kit is designed to enhance your vehicle’s airflow efficiency, supporting improved engine response and performance. Crafted for enthusiasts seeking to maximize their truck’s power potential, this intake system combines durability with functional design to deliver a noticeable upgrade in driving dynamics. Whether you're a daily driver or a weekend enthusiast, this kit helps your engine breathe better, resulting in smoother acceleration and increased torque, especially under load or during spirited driving. Constructed with high-quality materials, this intake kit features a rotationally-molded HDPE tube that maintains structural integrity under high temperatures and demanding conditions. The oversized, conical high-flow air filter ensures maximum airflow while providing long service intervals—up to 100,000 miles under normal highway conditions—thanks to its washable, reusable cotton filter media. A custom heat shield is included to protect intake air from engine bay heat, helping to maintain optimal air density and improve overall efficiency.
