Built for the 2020–2025 L5P 6.6L Duramax, the GMC Sierra 2500 HD Performance Air Intake by Wehrli (Stage 2, Sparkle Copper) replaces restrictive factory parts to improve airflow and response.

Featuring 4 in. piping and an intake horn over 1 in. larger than OEM, this kit improves velocity to the turbo and pulls cooler air via the hood Ram Air duct. Smooth bends add volume and a richer turbo note. The 10-gauge aluminum box seals to the hood port; silicone boots and stainless T-bolt clamps secure connections. Sparkle Copper powder coat. Bolt-on; no tuning required. Note: disable the factory air filter monitor to avoid a service message.
