If you're looking to boost your Duramax's performance, this HSP intake kit is where it's at. With a mandrel-bent 4.5-inch intake tube, it’s designed to maximize airflow like you wouldn't believe. You know how important it is to keep that air cool—every degree you let it heat up can cost you around 3 horsepower. That’s why HSP's got your back with their signature heat shield box that keeps the hot air out and lets the cool air in. Plus, the high-flow turbo mouthpiece? It outflows any other ported option out there, so you know you're getting the best of the best.

Now, let’s talk about the factory intercooler tubing on the 2003-2004 Duramax trucks. It’s pretty restrictive and, honestly, a bit of a ticking time bomb. The stock tubing is just 2.25 inches in diameter and has this awkward 90-degree boot at the intercooler that can fail without warning. I’ve seen it happen—when that hot side intercooler tube rubs against the power steering line, it can lead to a nasty boost leak that’ll have you pulling your hair out.

HSP’s solution? They’ve engineered a hot side tube that runs straight into the intercooler, using race-proven 5-layer silicone boots. This setup not only lowers temperatures and improves airflow but also gives you more clearance in those tight spots under the hood. It’s a smart design that really makes a difference when you’re pushing your truck to its limits.
