GMC Sierra 2500HD Performance Air Intake - Wehrli - 4in Intake Kit with Air Box - Chevy Orange - 01-04. Built for 2001–2004 Duramax LB7 trucks, this fabricated aluminum intake and air box replace restrictive factory parts to improve airflow and throttle response.

The 4 in. aluminum tube with smooth bends draws cool air from the inner fender to the turbo for improved horsepower, torque, and quicker response. A sealed air box with removable lid houses a dry filter, while the included hydrophobic pre-filter helps keep the MAF and turbo clean. Quality hardware, silicone boot, and stainless T-bolt clamps support a durable, bolt-on install. Finished in Chevy Orange powder coat. Made in USA.
