Introducing the HSP Diesel Cold Side Tube

The 605-HSP is your go-to choice for the HSP Diesel Cold Side Tube, specifically designed for 2017-2019 L5P Duramax-equipped Chevrolet and GMC trucks. Whether your truck is stock or modified, this upgrade is a smart decision that addresses a common issue with ease.

Why Upgrade to the HSP Diesel Cold Side Tube?

Changing out the factory cold side tube on your L5P is definitely worth considering. While it might seem like a minor detail, swapping out the cold side tube can significantly impact your truck's performance. The factory version is made of plastic, which can lead to unexpected failures without any warning signs. Don't let that happen to you!

What Makes the HSP Diesel Cold Side Tube Stand Out?

The original cold side on the L5P features a two-piece plastic design, which is not only weak but also creates multiple potential failure points. In contrast, the HSP Diesel L5P Cold Side Tube is crafted from durable mandrel-bent aluminum and comes with a metal adapter and high-strength silicone boots for installation. This design eliminates those failure points, keeping you safely on the road. Plus, installation is straightforward and requires no tuning, allowing you to upgrade your truck without any hassle. With the powder coat options available, you can tidy up your engine bay while boosting your truck's reliability—all in one go!

• (1) L5P Cold Side Adapter
