GMC Sierra 2500 Performance Air Intake — Wehrli Intake Resonator Pipe, Bengal Blue, 2020–2025. This 4-inch mandrel-bent aluminum pipe replaces the stock resonator, cleans up the bay, and improves airflow to the factory turbo.

Built for the 6.6L L5P Duramax with the factory VGT turbo, it retains the OEM air box for easy maintenance while reducing restriction and removing intake silencers for a more pronounced turbo and engine note. The Bengal Blue powder coat is durable and built to last. Installs with basic hand tools; no tuning required.
