Description
USP Marine Tuning High-Flow Boost Pipe Kit for Mercury Verado 350-400The factory boost pipe on the Verado 350 400 is plastic, narrow, and a known boost leak culprit. The USP Marine High Flow Boost Pipe Kit replaces it entirely with mandrel bent 2. 5" aluminum tubing and 4 ply stepped silicone couplers the same construction we use in our 1000HP automotive turbo builds. We also include the damage prone factory coupler between the boost valve and intake manifold, one of the most common and hardest to diagnose leak points
The factory boost pipe on the Verado 350-400 is plastic, narrow, and a known boost leak culprit. The USP Marine High-Flow Boost Pipe Kit replaces it entirely with mandrel-bent 2.5" aluminum tubing and 4-ply stepped silicone couplers — the same construction we use in our 1000HP automotive turbo builds. We also include the damage-prone factory coupler between the boost valve and intake manifold, one of the most common and hardest-to-diagnose leak points on these engines. The result is a boost leak-free setup, improved airflow, and a clean wrinkle black powder coat finish that looks factory-plus.
