Product Description

The aFe **46-20424-B BladeRunner Hot & Cold Charge Pipe Kit** is a performance upgrade designed for **2019-2025 Chevrolet Silverado 1500** and **GMC Sierra 1500** trucks equipped with the **2.7L turbo-charged L4 engine**. This BladeRunner kit replaces the factory plastic charge/intercooler tubes with **mandrel-bent aluminum pipes** featuring a **2.5" hot side** and **3" cold side**, which promote smoother airflow, reduced restriction, and minimized pressure loss between the turbocharger and intake system. These improvements help increase turbo efficiency, boost horsepower and torque potential, and lower intake air temperatures for enhanced performance.

Finished in durable **wrinkle black powder coat** for corrosion resistance and visual appeal, the kit includes **premium 5-ply silicone couplings**, **stainless-steel spring-loaded T-bolt clamps**, and **factory-style quick-connect adapters** with O-ring seals for a secure and leak-free installation. **1/8" NPT ports** allow integration of optional sensors or water/methanol injection systems. Designed as a **direct replacement** for the restrictive OE charge pipes and using all factory mounting points, this BladeRunner upgrade is ideal for enthusiasts seeking improved throttle response and airflow efficiency on their GM 1500 L4 2.7L Turbo trucks.
