(1) USP Marine Tuning MAX+ Performance Top Cowling For Verado L6 Engines
(1) USP Marine Tuning High-Flow Air Intake Pipe For Verado 350-400HP Engines
This replaces factory part # (8M0095505, 8M0095507, 8M0095507, 888988021, 8M0095506). The factory boost pipe is constructed of plastic and is extremely narrow resulting in an airflow restriction. The USP Marine pipe is constructed out of mandrel bent 2.5" aluminum tubing with 4 ply stepped silicone couplers. We also included the damage-prone factory replacement coupler, connecting boost valve to the intake manifold. We have seen countless factory couplers damaged and causing pesky boost leaks that are very hard to diagnose. By utilizing the boost pipe kit and included coupler, the kit will allow for maximum airflow and that extra insurance policy knowing you will never have a leak. The piping is powder coated with a wrinkle black durable finish for an OEM+ look.
(1) USP Marine Tuning Billet Aluminum High-Flow Fuel Filter Kit For Verado Engines
This replaces factory part # (879885K, 879885Q). A proper fuel filter is an important part of any fuel system. They are in place to provide a barrier for potential debris and contaminants before they reach the injectors. After carrying boxes of the plastic OEM in-line filters (Quicksilver 879885Q) for trips offshore, we decided to make a change. Made from billet aluminum, the USP Marine Billet In-Line High Flow Fuel Filters are built to withstand the harsh marine environment. Crafted with the same engineering we use in the car world, the filters also provide optimum flow for performance applications.
