Wehrli 17-19 Chevrolet 6.6L L5P Duramax Driver Side 3in Intercooler Pipe - WCFab Grey

If you're working on your 2017-2019 Chevrolet Silverado or GMC Sierra with the 6.6L L5P Duramax engine, this Wehrli 3-inch driver side intercooler pipe is a solid upgrade. It directly replaces the factory two-piece, 2 1/2-inch pipe, which can be a bottleneck for airflow, especially if you've made other modifications to your engine.

This pipe is well-built with a durable WCFab Grey powder coat finish, designed to handle higher boost and temperature than the stock component. It comes with upgraded silicone boots and stainless steel T-bolt clamps that are more reliable than the factory parts, helping to prevent leaks or blown boots under pressure. Installation is straightforward, as it’s a bolt-on part that doesn't require any tuning or other modifications to your truck's stock setup.

This is a direct replacement for GM part number 87839947 and is a popular choice for Duramax owners looking for improved airflow and reliability from their intercooler system.
