Wehrli 03-07 Dodge 5.9L Cummins Driver Side 3in Replacement Intercooler Pipe - Gloss Black

When you're looking to make sure your 5.9L Cummins is running at its best, especially if you've increased boost pressure beyond stock, a leaky intercooler pipe can really hurt performance. This driver side 3-inch intercooler pipe from Wehrli Custom Fabrication is designed to replace the factory plastic pipe, which is known to develop leaks under higher pressures. It's a direct bolt-on replacement that works with your stock intake horn and intercooler.

What you get in this kit is a mandrel-bent aluminum pipe, which offers a smooth, consistent inner diameter for better airflow compared to the stock piece. It also comes with silicone boots and stainless steel T-bolt clamps. These clamps are a big step up from the standard worm-gear style clamps, providing a more secure and leak-free seal that's crucial when you're pushing more boost. The pipe is finished in a durable gloss black powder coat, which not only looks good but also adds a layer of protection. This part is designed as a direct fit, meaning no other modifications or upgrades are needed for installation on a stock truck.

To complete the upgrade and ensure you've addressed both sides of the intercooler piping, Wehrli offers a matching passenger side pipe. This driver side pipe is a solid option for anyone looking to eliminate boost leaks and improve the reliability of their forced induction system.
