Overview

The Wehrli Custom Fabrication High Flow Y-Bridge Kit is an engineered solution to enhance the performance of your 6.6L L5P Duramax diesel engine. It is compatible with 2017-2026 Chevy Silverado and GMC Sierra 2500/3500 HD trucks, supporting both stock and high-horsepower builds.

The kit offers 33% more airflow than the OEM bridge and ensures even distribution of charged air to both engine cylinder heads. It also features integrated MAP sensor mounting bosses that protect the sensors from oil and soot buildup, thereby increasing sensor life and maintaining accurate readings. The enlarged air inlet tract is port-matched to the throttle valve to maximize the flow path. This emissions-compatible, bolt-on upgrade works with stock trucks, requires no tuning, and is compatible with OEM and aftermarket air intake systems and drop-in turbo upgrades.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
