Wehrli 17-19 Chevrolet 6.6L L5P Duramax Driver Side 3in Intercooler Pipe - Gloss Black

If you're working on a 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or a GMC Sierra 2500 HD or 3500 HD, equipped with the 6.6L L5P Duramax engine, this driver side intercooler pipe from Wehrli is a solid upgrade. It directly replaces the factory two-piece, 2 1/2 inch pipe with a larger, single 3 inch pipe, which helps improve airflow from the turbocharger to the engine.

This pipe is made from durable aluminum and finished in a gloss black powder coat to resist corrosion and look good under the hood. It comes with upgraded silicone boots and stainless steel T-bolt clamps that are built to handle higher pressure and temperatures than the stock components, helping to prevent leaks or blown boots. This is a straightforward bolt-on installation that doesn't require any tuning to see the benefits.
