BD Diesel Turbo Intake Horn - 2017-2022 Chevy/GMC 2500/3500 6.6L Duramax

Once you put a bigger turbo on an L5P Duramax, the plastic factory turbo inlet becomes the weak link. BD's Turbo Intake Horn (1045630) replaces it with a 3-1/2 in. stainless piece built to feed an aftermarket charger properly.

It's made to pair with BD's Screamer turbo and other aftermarket turbos on 2017-2022 GM 2500/3500 trucks.

Why we like it

• 409 stainless steel instead of factory plastic
• TIG welded, then black powder coated for a clean look under the hood
• 3-1/2 in. inlet sized for aftermarket turbo flow
• Direct replacement for the factory inlet
