aFe BladeRunner 3” Cold Side Intercooler Tube – 2017–2019 L5P 6.6L Duramax

Replace Your Restrictive Factory Tube with aFe’s High-Flow, TIG-Welded Upgrade

The aFe BladeRunner 3” Cold Side Intercooler Tube is a must-have upgrade for any 2017–2019 Chevy Silverado or GMC Sierra HD equipped with the 6.6L L5P Duramax diesel engine. Say goodbye to the brittle, airflow-limiting plastic OEM charge pipe and unleash more torque, lower EGTs, and stronger throttle response with this bolt-on aluminum performance upgrade.

Made from 3-1/2” mandrel-bent, aircraft-grade aluminum tubing, this intercooler tube flows cooler air more efficiently to your intake manifold while withstanding extreme heat and boost pressure. Whether you’re towing, tuning, or racing — it’s designed to handle serious diesel performance.

 Why Upgrade to the aFe BladeRunner Intercooler Tube?

  • ✅ Replaces restrictive OEM cold-side charge pipe
  • ✅ 3.5” mandrel-bent aluminum for max airflow & power
  • ✅ Lowers EGTs and reduces turbo lag
  • ✅ TIG-welded construction – built for high boost durability
  • ✅ Includes a billet quick-connect adapter for a factory-style fit
  • ✅ One (1) 1/8” NPT port for pressure sensors or meth injection
  • ✅ Retains OEM air temp sensor location
  • ✅ Finished in wrinkle black powder coat with laser-cut aFe logo badge
