The GMC Sierra 3500 Performance Air Intake by Wehrli is a high flow intake horn, specifically designed to enhance the performance of your vehicle. Available in the unique Sparkle Granny Smith finish, this intake horn is crafted to fit `01-`04 models, ensuring a precise and optimal upgrade for your truck's engine.

Designed to replace the restrictive OEM turbo mouthpiece, the Wehrli High Flow Intake Horn significantly boosts the airflow to your turbocharger, leading to improved engine performance and throttle response. Ideal for stock and performance aftermarket setups, this intake provides a notable power increase, with potential HP gains of 10-15 on max-effort tuned trucks and up to 20 HP with upgraded turbochargers. Its precision CNC-machined cast aluminum construction and custom powder coat finish not only ensure durability but also a perfect fit. Compatible with factory and aftermarket intakes, it’s an impeccable addition for automotive enthusiasts looking to optimize their vehicle’s performance.
