HSP Diesel Cold Side Tube for 2017-2019 L5P Duramax Trucks

The 605-HSP is your go-to solution for upgrading the cold side tube in your 2017-2019 L5P Duramax-equipped Chevrolet and GMC trucks. Whether your truck is stock or modified, this easy-to-install upgrade is a smart addition that addresses a common issue with minimal hassle.

Why Consider the HSP Diesel Cold Side Tube?

Replacing the factory cold side tube on your L5P is a worthwhile investment. While it might seem like a minor component, upgrading this part can make a significant difference. The factory cold side pipe 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 stock cold side design is a two-piece plastic setup, which not only lacks durability but also introduces multiple potential failure points. In contrast, the HSP Diesel L5P Cold Side Tube is crafted from mandrel-bent aluminum and features a metal adapter along with high-strength silicone boots for installation. This design eliminates those weak points, helping you stay on the road longer.

Installation is a breeze, as it fits seamlessly with all factory components and requires no tuning! You can enjoy peace of mind knowing that your truck is reliable, and with the powder coat options available, you can spruce up your engine bay at the same time.
