Turbo Horn Upgrade for GM 6.6L Duramax

If you're upgrading your L5P Duramax for better airflow and performance, one of the most overlooked components is the turbo intake horn. The BD Diesel Turbo Intake Horn is a direct replacement for the restrictive plastic factory inlet pipe found on 2017–2022 GM HD trucks. Designed with performance in mind, this intake horn is built from 3.5-inch 409 series stainless steel tubing, TIG welded for strength and finished with a sleek black powder coat to stand up against heat and corrosion.

Handles High Boost Pressures with Ease

What makes this a worthwhile upgrade is its ability to reduce restriction and improve airflow into the turbo—especially important when you're running a larger aftermarket unit like BD’s Screamer Turbo or any other performance L5P turbo. The stock plastic horn simply wasn’t made to handle higher boost pressures or flow demands from upgraded systems. This is where the BD horn steps in, delivering a more durable and efficient path for incoming air. What's more, the install is straightforward and typically takes about an hour and fifteen minutes. It's a true drop-in component for those who are serious about optimizing airflow and maximizing turbocharger efficiency. However, it's important to note that this part isn't recommended for use with a stock turbo unless you're pairing it with custom tuning to fully dial in performance.
