The GMC Sierra 2500 Performance Air Intake by Wehrli, featuring the High Flow Intake Horn in Sparkle Granny Smith, is a must-have upgrade for 2001-2004 Chevy Silverado and GMC 2500/3500 HD trucks with the 6.6L Duramax Diesel engine. This unique part is engineered to optimize airflow for enhanced performance and response, making it a desirable addition for automotive aficionados.

The heart of this performance air intake lies in its expertly designed 4-inch high flow cast aluminum turbo intake horn. It effectively replaces the restrictive OEM turbo mouthpiece, allowing for an increase in airflow to your turbocharger, which in turn sharpens engine performance and throttle response. Compatible with both factory IHI turbochargers and selected aftermarket intakes, it offers improved spool-up and horsepower—ideal for those looking for that extra boost to their vehicle’s power.
