Introducing the HSP Diesel Cold Side Tube

The 605-HSP is your go-to solution for the 2017-2019 L5P Duramax equipped Chevrolet and GMC trucks. If you're looking to upgrade your truck, this cold side tube is a fantastic option, whether your vehicle is stock or modified. It's a simple installation that addresses 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 may seem minor, swapping out this component can lead to significant improvements. The original cold side pipe is made of plastic, which is prone to failure without any warning. By upgrading to the HSP Diesel Cold Side Tube, you can avoid unexpected issues down the road.

What Makes the HSP Diesel Cold Side Tube Stand Out?

The factory cold side on the L5P features a two-piece plastic design, which is not only weak but also creates multiple points of potential failure. In contrast, the HSP Diesel L5P Cold Side Pipe is crafted from mandrel-bent aluminum and includes a metal adapter along with high-strength silicone boots for installation. This design eliminates those weak points, ensuring you stay on the road with confidence. Plus, you can install it using all the factory components, and no tuning is required! This means a hassle-free installation without any worries about performance issues afterward. With various powder coat options available, you can tidy up your engine bay while boosting your truck's reliability.

A Quick Note
