GMC Duramax Performance Air Intake - Wehrli - 4in with Air Box - Candy Red - 01-04. Built by Wehrli Custom Fabrication for 2001-2004 GM 6.6L Duramax LB7 trucks, it replaces restrictive factory parts so your turbo can breathe easier.

The fabricated 4 in aluminum tube and sealed air box use a dry filter to increase airflow, sharpen throttle response, and help lower intake temps by pulling cool air from the inner fender. Smooth bends aid velocity and bring out a richer turbo note. A removable lid simplifies checks, and the included Outerwears hydrophobic pre-filter helps keep the MAF and turbo cleaner. Hardware, silicone boot, seals, and stainless T-bolt clamps are included. Candy Red powder coat, installs with basic tools, no tuning required. Made in the USA.
