HSP Diesel Cold Side Tube for 2017-2019 L5P Duramax

The 605-HSP is your go-to solution for upgrading the Cold Side Tube on your 2017-2019 L5P Duramax-equipped Chevrolet and GMC trucks. Whether you’re running a stock setup or have made some modifications, this upgrade is a smart choice that addresses a common weak point in your truck's performance.

Why Upgrade to the HSP Diesel Cold Side Tube?

Let’s talk about the factory cold side tube on the L5P. It might not seem like a big deal, but swapping it out can truly make a difference. The original plastic design is prone to failure without any warning, which can leave you in a tough spot. By replacing it with the HSP Diesel Cold Side Tube, you’re taking a proactive step towards reliability.

What Makes the HSP Diesel Cold Side Tube Stand Out?

The factory cold side setup features a two-piece plastic design that can be weak and has multiple failure points. In contrast, the HSP Diesel Cold Side Tube is crafted from durable mandrel-bent aluminum, paired with a metal adapter and high-strength silicone boots. This design eliminates potential failure points, keeping you on the road with confidence. Plus, installation is a breeze—no tuning is required, and it fits seamlessly with all factory components. With the available powder coat options, you can tidy up your engine bay while boosting your truck's reliability.
