Chevrolet Silverado 2500 Performance Air Intake - Wehrli - Stage 2 - Candy Red - `20-`24 is a bolt-on high-flow intake designed for 2020-2024 L5P 6.6L Duramax Silverado / Sierra HD trucks. It replaces restrictive factory plastic parts with a fabricated aluminum 4" intake and airbox to increase airflow to the turbo.

Constructed from 10-gauge aluminum with smooth aerodynamic bends, the Stage 2 kit improves intake air velocity and volume while drawing cold air through the hood ram-air duct and inner fender. The intake horn is over an inch larger than OEM to reduce restriction ahead of the turbo inlet. Finished in Wehrli’s custom candy red single-stage powder coat, the assembly includes a dry filter, Outerwears pre-filter cover, high-quality silicone boot, and stainless-steel T-bolt clamps. Compatible with stock trucks; no tuning required. NOTE: Failure to disable the air filter monitor system will result in a service air filter message and will require a dealer reset.
