Overview

It moves the air filter away from the engine compartment to draw in cooler, denser air, which improves combustion and performance. This system offers better airflow than the factory air filter box.

Show original supplier description

By relocating the air filter away from the heat of the engine bay, this system draws in cooler, denser air, leading to more efficient combustion and optimal power output. Its cylindrical design and large diameter tube facilitate superior airflow compared to restrictive factory air filter boxes. This cold air intake system includes a premium, reusable air filter that is easy to clean, ensuring long-lasting performance. Installation is straightforward, providing an immediate increase in performance. This cold air intake is specifically designed to fit the 2014-2018 Chevrolet Silverado 1500 4WD and the 2014-2018 GMC Sierra 1500 4WD models with 5.3L and 6.2L engines.
