Improve charge-air flow on select 2020–2026 Chevrolet Silverado and GMC Sierra trucks and SUVs equipped with the 3.0L Duramax diesel engine. The aFe BladeRunner 46-20454-B charge pipe kit replaces restrictive factory plastic and rubber components with a free-flowing aluminum hot-side tube and reinforced silicone cold-side hose. Smoother transitions between the tubing and couplings help reduce turbulence and pressure loss, supporting improved throttle response, horsepower, and torque potential.

This kit is engineered for strength, durability, and reliable boost retention. The hot-side tube is TIG-welded from aluminum, while the cold-side connection uses heavy-duty, five-ply polyester-reinforced silicone. Premium stainless-steel SmartSeal clamps provide secure connections, and the factory-style billet aluminum quick-connect adapter uses an O-ring seal for a precise, leak-resistant fit. The included ports support the installation of sensors or water-methanol injection equipment, helping you monitor and optimize vehicle performance.

Finished with a wrinkle-black powder coating, the aFe BladeRunner charge pipe kit resists heat and corrosion while adding a clean, custom appearance under the hood. A laser-etched aFe Power logo provides a distinctive finishing detail. This automotive application is intended for compatible GM 3.0L Duramax LM2 and LZ0 configurations; verify vehicle and engine compatibility before ordering.
