The factory plastic resonator pipe on the Verado L6 350-400 is restrictive, crack-prone, and the number one source of the boost leaks that rob these engines of power. The USP Marine High-Flow Air Intake Pipe replaces it with 4-ply wire-reinforced silicone piping, CNC-machined aluminum adapters, and 316 stainless clamps throughout — the same spec used in our 1000HP turbo builds at USP Motorsports. The result is +30% CFM over stock, sharper throttle response, lower intake air temps at WOT, and that unmistakable supercharged induction sound.
