GMC Sierra 2500 HD Air Intake Pipe - Wehrli - 4in. OEM Air Box - Gloss White - 20-25. A mandrel-bent aluminum resonator-delete that keeps the factory air box on 2020-2025 L5P Duramax trucks.

This 4 in. pipe replaces the stock plastic duct and resonator to reduce restriction and tidy the bay. It keeps the OEM panel filter for easy service, needs no tuning, and installs with basic tools. For L5P VGT trucks, it adds sharper response and a more pronounced turbo/engine note. Made in the USA with gloss white powder coat.
