The GMC Sierra Performance Air Intake by Wehrli Custom Fabrication - Stage 2, 4in in Bengal Blue is engineered to boost your vehicle's performance. Designed specifically for the `17-`19 Duramax L5P, this intake kit enhances engine function and provides a distinct visual appeal that matches your personal style and ride quality.

This high-performance air intake system replaces the standard restrictive plastic parts with a high-flow, fabricated aluminum pipe and air box enclosure. It significantly increases airflow to the turbo, resulting in improved horsepower and torque. The design offers quicker throttle response and cooler intake temperatures, bringing cold air through the hood Ram Air duct and inner fender for optimal efficiency. With 4" piping featuring smooth aerodynamic bends, this kit increases intake air velocity and volume, producing a more aggressive engine and turbo sound during acceleration.
