If you're looking to ditch that flimsy stock cold side charge pipe in your Duramax, let me tell you, this HPS Performance Cold Side Charge Pipe Kit is the way to go. I swapped mine out, and it was like night and day. The OEM plastic just doesn’t cut it, especially when you’re pushing your truck to its limits. This kit features a robust 3.5" mandrel-bent stainless steel tube that really opens up airflow to your engine. Trust me, your turbo will thank you for it, and you’ll notice a significant drop in exhaust gas temperatures (EGTs) too, which is a huge win for the engine’s longevity.

What I really appreciate about this kit is the attention to detail. The 4-ply reinforced, oil-resistant fluoro-lined silicone boots are built to handle the oil blow-by that’s all too common in the 6.6L Duramax Diesel LML engines. You won’t have to worry about those boots wearing out on you anytime soon. Plus, the stainless steel spring-loaded T-bolt clamps are a nice touch. They adjust to temperature and pressure changes during operation, so you can forget about pesky boost leaks down the line.
