The Chevrolet Silverado 2500 HD Performance Air Intake by Wehrli offers a marked improvement for Chevrolet Silverado or GMC 2500/3500 HD trucks from the years 2001 to 2004. This high flow, 4-inch performance turbo intake is meticulously crafted in fine texture black to enhance your vehicle's performance.

Engineered for the 6.6L Duramax Diesel, this performance air intake replaces the restrictive OEM turbo mouthpiece, significantly increasing airflow to your turbocharger. The result? Enhanced engine performance and better throttle response. It's compatible, whether your truck runs on the factory IHI Turbo, upgraded IHI Turbos, or aftermarket intakes. Experience quicker spool-up times and horsepower gains, with max-effort trucks witnessing an increase of 10-15 HP and those with upgraded turbochargers seeing up to 20 HP improvements. This is a bolt-on upgrade, requiring no additional tuning or modifications.

Features

• True 4" inlet turbo intake for optimized airflow
• Precision CNC machined cast aluminum construction
• Flows 40% better than stock parts
• Includes mounting hardware and an O-ring seal
• Custom powder coat finish in your chosen color
• Made in the USA
