It includes a 4-inch diameter by 6-inch long, 4-ply aramid-reinforced silicone hump hose and two T-bolt clamps. The kit is designed for the hot (pressure) side of the turbo-to-intercooler piping and replaces worn or split hoses that can cause boost leaks, loss of power, and increased exhaust temperatures. It provides a durable, heat-resistant connection that restores proper CAC system integrity.
