4 Ply Hump Hose 2in I.D. x 3in long - Black

The 4 Ply Hump Hose 2in I.D. x 3in long in black from VIBRANT PERFORMANCE is a specialized silicone tubing coupler engineered for high-performance automotive cooling and intercooler systems. This hump-style connector is purpose-built for applications where space constraints demand a curved transition between hard lines or components, making it essential for turbo kits, supercharger installations, and custom cooling circuits. Mechanics and fabricators choose this coupler when routing must navigate tight engine bays or when OEM tubing layouts require flexible bridging without compromising flow integrity or durability under boost conditions.

Constructed from premium four-ply reinforced silicone, this hose delivers superior strength and flexibility compared to standard single-ply alternatives, allowing it to withstand elevated intake and coolant temperatures while maintaining structural integrity under pressure cycling. The 2-inch inner diameter (I.D.) accommodates moderate to high flow volumes typical of forced-induction systems, while the 3-inch length provides just enough curvature to navigate engine compartment obstacles without creating excessive restriction or dead zones in the line. The reinforced ply construction resists ballooning and collapse, ensuring consistent flow characteristics across a wide operating temperature range—critical for maintaining boost response and thermal management efficiency in modified vehicles.

This coupler is ideal for custom intake manifold builds, intercooler piping upgrades, and radiator bypass applications on turbocharged and supercharged engines. Its compact 3-inch length makes it particularly suited for tight engine bay fitment on modern performance cars where stock spacing is minimal. Installation requires standard hose clamps on each end, and compatibility extends to any cooling or intake system using 2-inch I.D. tubing—verify your hard-line OD and clamp style before ordering to ensure proper fit and secure sealing under boost.
