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. This Cold Side Tube is a fantastic choice, whether you're sticking with stock or looking to enhance your ride. With its straightforward installation, it’s an upgrade that just makes sense!

Why Upgrade to the HSP Diesel Cold Side Tube?

You might wonder why you should consider changing the factory cold side tube on your L5P. While it may seem minor, swapping out this component can significantly impact your truck's performance. The factory cold side tube is made of plastic, which is prone to failure without any warning. Making this change could save you from unexpected issues down the road.

What Makes the HSP Diesel Cold Side Tube Different?

The factory cold side tube features a two-piece plastic design, which is not only weak but also has multiple failure points. In contrast, the HSP Diesel L5P Cold Side Pipe is crafted from durable mandrel-bent aluminum. It comes with a metal adapter and high-strength silicone boots for easy installation. This design eliminates those potential failure points, keeping you on the road with confidence. Plus, you can install it using all your factory components without needing to tune your truck! With various powder coat options available, you can tidy up your engine bay while boosting your truck's reliability.
