Description
Product Overview
The K&N Performance Air Intake System (Model 57-0421) features a Rund‑shaped, high‑flow filter housed in a robust aluminum enclosure. Engineered by K&N Engineering, this intake replaces the restrictive factory setup, allowing a greater volume of cool, oxygen‑rich air to reach the combustion chambers. Weighing just 2.91 lb and measuring 9″ L × 9″ W × 9″ H, it fits seamlessly in the left‑hand position of most compatible vehicles. Included dyno‑tested horsepower and torque data verify real‑world gains, and the system is covered by a No‑Hassle Lifetime Limited Warranty.
Usage
Designed for street, highway, and light‑towing applications, the intake excels in daily commuting, weekend road trips, and uphill climbs. Drivers seeking sharper throttle response and a more aggressive engine note will notice immediate benefits during acceleration. The system’s durable construction also protects the engine from dust and debris, making it suitable for both city traffic and off‑road adventures.
