When it comes to upgrading your truck's performance, a solid cold air intake is a game changer, and I can personally vouch for the HSP intake. This isn't just some flashy accessory; it’s a serious piece of engineering that delivers real results. I’ve seen the dyno numbers—this bad boy can add an impressive 20 horsepower and a whopping 58 pounds of torque on average. That means you’re not just getting a boost in power; you’re getting the kind of performance that makes a difference on the road and off.

One of the standout features is the heat shield box. It’s designed to keep the intake air nice and cool by separating it from the hot air under the hood. Instead of sucking in that heat, it draws in fresh, cold air from the headlight bezel and fender port. Trust me, that makes a noticeable difference in performance. Plus, the 4.5-inch mandrel-bent tubing provides a smooth, unrestricted airflow path, which is crucial for getting the most out of your engine. This intake doesn’t just compete; it outperforms a lot of the other options out there.

And let’s talk about the filter. HSP teamed up with one of the best in the business to ensure you’re getting a filter that’s built to last. Good filtration is essential for the longevity of your turbocharger, and you don’t want to skimp on something that’s going to keep your engine running strong for years to come. Cheap intakes just can’t compare, and you’ll feel the difference in both performance and reliability.

Now, a quick heads-up: these components are designed for closed-course competition only. So, if you’re planning to hit the streets, keep in mind that it’s your responsibility to ensure your setup complies with all the regulations. These performance parts are meant for sanctioned racing, and using them on public roads is at your own risk.

By picking up this intake, you’re agreeing not to hold HSP Diesel responsible for any unlawful vehicle operation. Just something to keep in mind as you’re upgrading your ride.
