DIESELR High Flow Y-Bridge (2017-2024 Duramax 6.6L L5P)

3.5" High-Flow Y-Bridge Assembly
For Custom Racing Applications – L5P Duramax

Built for Big Power:
When you’re pushing serious air and fuel, the factory L5P Y-bridge becomes a major bottleneck. This 3.5" High-Flow Y-Bridge is designed to eliminate that restriction and deliver a direct, high-volume path to your intake runners—perfect for high-horsepower race builds.

Race-Ready Construction:
Crafted from 304 stainless steel with a TIG-welded finish for superior strength and durability. The 3.5” bead roll inlet ensures a secure connection under heavy boost, and a polished finish comes standard—ready to paint or leave as-is.

Precision Fit:
Bolts directly to OEM intake runners using factory hardware and seals. Includes bungs for MAP sensor and 1/8" NPT accessory.

Fitment:
Custom-fit for race-prepped 2017–2024 L5P Duramax engines. Intended for fabricated or custom intake systems only. Not compatible with OEM turbo or intercooler pipes.
