Description
High-Flow Performance Upgrade. The AFE BladeRunner 3-Inch Hot Charge Pipe enhances turbocharger efficiency by increasing airflow volume between the turbo and intercooler.

Durable and Heat-Resistant Build. Made from mandrel-bent aluminum, this charge pipe delivers strong, unrestricted flow with a textured black finish that resists heat, corrosion, and engine bay wear. Included heavy-duty silicone couplings and T-bolt clamps ensure a secure, leak-free connection under high boost pressures.
Installation. This product installs using included couplings and clamps. Basic hand tools required; no cutting is necessary.
Application. This AFE BladeRunner 3-Inch Hot Charge Pipe in Black is designed to fit 2017-2019 Sierra 2500 HD models equipped with the 6.6L Duramax engine.
