The Chevrolet Silverado 3500 Performance Air Intake by Wehrli is a high-performance upgrade designed for the 2001-2004 Chevrolet Silverado or GMC 2500/3500 HD trucks with the 6.6L Duramax Diesel engine. This 4-inch High Flow Intake Horn in a striking Sparkle Bomber Orange finish offers unparalleled airflow enhancements, optimizing the performance of your vehicle's turbocharger.

Crafted from precision CNC-machined cast aluminum, this intake horn replaces the restrictive OEM turbo mouthpiece, significantly increasing airflow to the turbocharger. This enhancement improves engine performance and throttle response. It's compatible with both factory IHI Turbos and a variety of upgraded aftermarket intake systems. For max-effort tuned trucks, expect gains of 10-15 HP, while those with upgraded turbochargers can experience improvements up to 20 HP. Notably, it’s custom powder coated and made in the USA, ensuring both quality and style.
