Introducing the HSP Diesel Cold Side Tube

The 605-HSP is your go-to solution if you own a 2017-2019 L5P Duramax-equipped Chevrolet or GMC truck. This Cold Side Tube is a fantastic upgrade that’s perfect for both stock and modified trucks. Say goodbye to common issues with this easy-to-install enhancement—it's a no-brainer!

Why Upgrade to the HSP Diesel Cold Side Tube?

Replacing the factory cold side tube on your L5P is definitely worth considering. While it might seem like a minor component, upgrading your cold side tube can make a significant difference. The factory cold side is made of plastic, which is prone to failure without any warning. Why risk it?

What Makes the HSP Diesel Cold Side Tube Stand Out?

The original cold side on the L5P features a two-piece plastic design, which not only lacks strength but also introduces multiple potential failure points. In contrast, the HSP Diesel L5P Cold Side Pipe is crafted from durable mandrel-bent aluminum. It comes with a metal adapter and high-strength silicone boots for a secure installation. This thoughtful design eliminates those weak points, keeping you on the road worry-free. Plus, you can install it using all factory components without needing any tuning! With various powder coat options available, you can tidy up your engine bay while boosting your truck's reliability.
