The Mishimoto DuraCore 3-Inch Straight Hump Silicone Intercooler Coupler, part number MMDCC-30HBK, is designed to create a secure connection between compatible intercooler, intake, and charge piping. Its straight hump configuration adds flexibility to help accommodate engine movement, vibration, and alignment changes while maintaining a dependable, leak-resistant seal. This makes it a practical choice for custom intercooling systems and high-performance vehicle builds.
Constructed with Mishimoto DuraCore technology, this coupler features a five-layer silicone design with embedded heat-resistant fibers. The inner DuraCore layer provides enhanced resistance to heat, pressure, fuel, and oil compared with standard silicone hose materials. This durable construction helps reduce the risk of leaks, blowouts, and premature wear in demanding high-boost applications while supporting reliable long-term performance.
The 3-inch connection size is suited for compatible intercooler piping and fabrication projects where additional flexibility is needed at the joint. Reinforcing construction helps the coupler maintain its shape and connection integrity under pressure, while the hump-style design supports easier alignment during installation. Pair it with properly sized clamps for a secure installation and dependable service in custom intake or intercooler systems. Mishimoto backs this automotive component with engineering focused on strength, fitment, and performance.
Whether you are routing charge piping through a tight engine bay or completing a custom intercooler setup, the Mishimoto MMDCC-30HBK provides a robust connection point without unnecessary complexity. Its heat- and pressure-resistant silicone construction is built to withstand the conditions commonly found in turbocharged and performance applications.
