BD Diesel 17-22 Chevy/GMC 2500/3500 Duramax 6.6L Turbo Intake Horn

Already running an upgraded turbo on your 2017-2022 Chevrolet Silverado 2500 HD or 3500 HD, or GMC Sierra 2500 HD or 3500 HD with the 6.6L Duramax engine? This turbo intake horn is the next piece of the puzzle. It swaps out the restrictive factory plastic turbo inlet pipe for a larger, smoother 3-1/2 inch diameter stainless steel tube. This change helps the turbo breathe more freely, especially when paired with aftermarket turbos or custom tuning.

This intake horn is constructed from 409 stainless steel tubing and features TIG welded construction for solid joints. It’s then finished with a black powder coating to protect against corrosion and give it a clean look under the hood. It’s designed as a direct replacement for the stock pipe, making installation straightforward, though it's not recommended for use with the factory turbocharger unless you're also updating the engine's computer tune.
