2017-2019 Duramax Driver Side Intercooler Pipe Kit (L5P-INT-A041)

When you tune your truck or go bigger on your turbo, one of the things that can hold it back is the stock driver side charge pipe. It's just too restrictive. Our pipe opens up the charge system for smoother airflow, with every compound bend designed to keep that air moving, and the included silicone couplers replace the weak OEM ones that tend to balloon or split under high pressure. Paired with T-bolt clamps over bead-rolled ends, the install is solid and leak-free. We build it as a two-part pipe, which makes for a much easier install than fighting a one-piece pipe into the bay. Choose raw stainless or powder coated aluminum to match your engine bay, and it performs as good as it looks.

Part Number: L5P-INT-A041
