The GMC Sierra 3500 Performance Air Intake by Wehrli is a superior upgrade for your `01-`04 Sierra 3500, featuring a High Flow Cast Intake Horn in an impressive Bengal Red finish. Specifically engineered for enhanced airflow, this component improves engine performance and throttle response.

This air intake system is designed to replace the factory-installed restrictive OEM turbo mouthpiece, allowing up to 40% better airflow to your turbocharger. Compatible with both factory IHI Turbo and upgraded IHI Turbo units, it provides noticeable performance gains. The intake is perfectly suited for high-performance applications, offering additional horsepower—up to 15 HP for max-effort tuned setups and potentially 20 HP with upgraded turbochargers. Crafted in the USA from precision CNC-machined cast aluminum, this durable and corrosion-resistant component comes with an O-ring seal at the face of the turbocharger for airtight installation. Finished in a vibrant Bengal Red powder coat, it adds a robust look under the hood.
