GMC Sierra 3500 HD Air Intake Pipe - Wehrli - 4 in. OEM Air Box - Gloss White (2020–2025). A bolt-on intake resonator pipe that replaces bulky factory plastic to improve airflow and clean up the engine bay.

Designed for the 6.6L L5P Duramax with the factory VGT turbo, this mandrel-bent aluminum pipe retains the OEM air box and panel filter for easy service. The durable gloss white powder coat and straight-through 4-inch path reduce restriction and remove the stock silencers for a more pronounced turbo and engine note. Installs with basic hand tools, requires no tuning, and fits stock trucks. Direct replacement for GM 84841229, 84841225, 84262962. Made in the USA.
