Chevrolet Silverado Performance Air Intake - Wehrli - 4in Intake Pipe - WCFab Grey (2020-2024). A direct-fit resonator-delete pipe for 6.6L L5P Duramax trucks with the OEM air box that opens airflow and cleans up the engine bay.

Built from 4 in mandrel-bent aluminum, this upgrade replaces the bulky plastic resonator/ducting and engine cover, reducing restriction to feed the VGT turbo while adding a more pronounced turbo and engine note. It retains the factory panel filter and air box for easy service, installs with basic hand tools, and requires no tuning. Finished in durable WCFab Grey powder coat with silicone boots and stainless T-bolt clamps. Only compatible with the OEM air box; not for S&B, Banks, AFE, or other aftermarket intakes.
