2017-2019 GM 2500HD/3500HD 6.6L L5P Duramax Intercooler Pipes & Intake Accessories

Upgrading the factory intercooler on your 2017-2019 GM 6.6L Duramax L5P is a great way to improve the overall power an performance of your ride; however, without any tubing upgrades your engine will still experience restrictive airflow during any high-performance applications such as towing or overlanding. Equipping your ride with larger intercooler tubes is a great way to promote additional horsepower and fast heat dissipation when you're out pushing things to the limit. The premium construction of these tubes even allow for superior corrosion resistance and longer service life, keeping your Sierra/Silverado 2500/3500HD out on the road for longer.
