Product Description

The Roush 421238 Cold Air Intake Kit is a performance upgrade designed specifically for 2011-2014 Ford F-150 trucks equipped with the 5.0L V8 engine. This cold air induction system replaces the restrictive factory intake with a complete intake tube, airbox, and high-flow oiled filter to improve engine breathing. The result is better throttle response, increased airflow efficiency, and an enhanced engine sound that complements both daily driving and light performance use.

Installation is straightforward and can typically be completed in under an hour without any cutting, drilling, or PCM recalibration. Built using OEM CAD data, the intake tube and components offer excellent fit and structural stability. The washable, reusable air filter helps reduce long-term maintenance costs while maintaining protection against contaminants. Backed by Roush performance design, this intake kit enhances both the look and the function of your F-150's engine bay.
