It includes a 4-inch inner diameter, 6-inch long silicone hump hose reinforced with 4 plies of aramid, plus two hose clamps. The silicone material handles high temperature and pressure from the turbocharger outlet, preventing boost leaks that can reduce power and fuel economy. Install this when you find cracks, swelling, or separation at the charge air hose connections.
