The GMC Sierra 3500 HD Performance Air Intake by Wehrli offers unparalleled engine intake performance with its High Flow 4-inch design, available in Fine Texture Black. Made specifically for the 2001-2004 Sierra HD models, this air intake is an essential upgrade for enthusiasts looking to enhance their vehicle's performance by optimizing airflow directly to their turbocharger.

The Wehrli air intake replaces the restrictive OEM turbo mouthpiece with a precision CNC machined cast aluminum construction that promotes smoother and more efficient airflow. Compatible with both factory IHI Turbo and upgraded aftermarket intakes, it supports various performance setups. This meticulously engineered intake horn is designed to offer improved throttle response, quicker spool up, and potential horsepower gains of 10-15 HP in standard configurations, and up to 20 HP when paired with upgraded turbochargers. Made in the USA, the unit's fine texture black powder coat offers not only functionality but durability.
