Introducing the HSP Diesel Cold Side Tube

The 605-HSP is your go-to upgrade for the 2017-2019 L5P Duramax equipped Chevrolet and GMC trucks. It's widely recognized as the HSP Diesel Cold Side Tube, and it’s a fantastic option whether your truck is stock or modified. This easy-to-install upgrade tackles a common issue, making it a smart choice for any truck owner.

Why Consider the HSP Diesel Cold Side Tube?

The factory cold side tube on the L5P is definitely worth replacing. While it might seem like a minor component, upgrading to a better cold side tube can significantly impact your truck's performance. The original plastic design is prone to failure, and you often won't see it coming until it’s too late.

What Makes the HSP Diesel Cold Side Tube Stand Out?

Unlike the factory cold side, which is a two-piece plastic design with multiple weak points, the HSP Diesel L5P Cold Side Tube is crafted from durable mandrel-bent aluminum. It features a metal adapter and high-strength silicone boots for a secure installation. This design eliminates potential failure points, keeping you safely on the road. Plus, you can install it using all the factory components without needing any tuning, making the process straightforward and worry-free. With the powder coat options available, you can tidy up your engine bay while boosting your truck's reliability.
