GMC Sierra 2500 HD Intercooler Pipe - Driver Side - Wehrli - High Flow 3in - Chevy Orange - 17-19. A direct hot-side upgrade that replaces the restrictive factory tube with a robust 3 inch pipe for clean, reliable airflow.

Built for the 2017-2019 6.6L Duramax L5P, this WCFab driver-side intercooler pipe swaps the stock two-piece 2.5 inch assembly for a high-flow, one-piece 3 inch design. It includes high-temp, high-pressure silicone boots and stainless T-bolt clamps to boost durability and curb blown boots. Finished in a durable Chevy Orange powder coat, it installs on a stock truck with no other modifications or tuning required. Replaces GM part number 87839947 and fits Chevrolet Silverado and GMC Sierra 2500/3500 HD models.
