The Chevrolet Silverado Performance Air Intake by Wehrli is the ultimate upgrade for your 2001-2004 Silverado or GMC 2500/3500 HD trucks equipped with the 6.6L Duramax Diesel engine. This high-flow cast aluminum turbo intake horn is finished in a vibrant Kiwi Green, ensuring both style and performance enhancements under the hood.

Designed to replace the restrictive OEM turbo mouthpiece, this intake horn significantly boosts airflow to your turbocharger, improving engine performance and throttle response. Whether equipped with a factory IHI Turbo, upgraded IHI Turbos, or aftermarket intakes, this product is engineered to deliver noticeable power gains. Max-effort tuned trucks can see improvements of 10-15 HP, while trucks with upgraded turbochargers might experience increases up to 20 HP. To achieve the best results, pair it with our 4" Cold Air Intake Kits, Stage 1 High Flow Bundle Kits, and custom performance tuning.
