The Chevrolet Silverado 3500 Performance Air Intake by Wehrli, featuring a 4-inch High Flow Intake Horn in Gloss Black, is designed for the 2001-2004 models. This high-performance air intake system is engineered to enhance the airflow to your engine, optimizing performance and improving throttle response for your Duramax diesel truck.

Constructed with precision and functionality in mind, this performance air intake replaces the restrictive OEM turbo mouthpiece, ensuring your turbocharger receives increased airflow. This results in improved engine performance, faster spool-up, and potential horsepower gains. Compatible with factory IHI Turbo or upgraded IHI turbos, it's the perfect upgrade for stock and modified trucks alike. Pair it with our custom performance tuning and aftermarket intake systems for maximum performance enhancements. Crafted from high-quality cast aluminum, this intake horn is precision CNC machined and boasts a sleek gloss black powder-coated finish.
