Description
Description
If you're chasing horsepower in your 2017–2024 Duramax 6.6L L5P, the factory Y-bridge is holding you back. This 3.5" High-Flow Y-Bridge from Dieselr replaces that restrictive factory bottleneck with a wide-open, direct-flow path to your intake runners—perfect for high-horsepower, race-tuned applications.
Whether you’re feeding a bigger turbo or running aggressive fueling, this is the Y-bridge serious Duramax builders rely on.
Race-Grade Construction That Doesn’t Back Down
- 3.5” Inlet: Bead-rolled to hold tight under high boost
- TIG-Welded 304 Stainless Steel: Built to take heat and pressure
- Polished Finish: Clean look out of the box, or ready for paint
- Sensor Ports Included: MAP sensor + 1/8" NPT accessory ready
This isn’t a shiny showpiece—it’s a workhorse part built to perform in the real world.
Direct Fit. Custom System Ready.
The Dieselr Y-Bridge bolts straight to your factory intake runners with OEM hardware and seals. It’s made for builders running custom intake setups, fabricated piping, or upgraded turbos—not for stock trucks.
Note: Not compatible with OEM turbo or factory intercooler piping.
