The GMC 2500 Performance Air Intake by Wehrli is a High Flow Intake Horn designed for the `01-`04 models. This precision-crafted upgrade comes in a semi-gloss black finish and is engineered to significantly enhance your vehicle's airflow, optimizing both performance and throttle response. Tailored for the 6.6L Duramax Diesel engine in GMC 2500 / 3500 HD trucks, this intake replaces the restrictive OEM turbo mouthpiece, providing a pathway for improved power delivery.

Featuring an impressive 4-inch diameter, this intake horn delivers the largest and highest flowing turbo inlet in its class. Built from precision CNC machined cast aluminum, the product ensures long-lasting durability and superior performance. Compatible with both factory and aftermarket setups, it offers exceptional gains—even more pronounced when paired with upgraded turbochargers, potentially boosting horsepower by up to 20 HP. The quality craftsmanship ensures a smooth transition to the turbo compressor cover for optimal airflow.
