Build a more reliable intercooler system with the Mishimoto DuraCore 4in Straight Hump Silicone Coupler. Engineered for custom fabrication and high-boost applications, this coupler serves as a critical link in your charge piping, providing the flexibility needed to absorb engine movement and vibration without compromising the seal.

Every Mishimoto DuraCore boot features a specialized synthetic inner layer that provides superior resistance to heat, pressure, fuel, and oil compared to standard silicone. This prevents the degradation and blowouts often seen in demanding environments. The 5-layer construction includes heat-resistant embedded fibers for maximum structural integrity under extreme pneumatic loads.

  • DuraCore technology offers a specialized inner layer for industry-leading resistance to fuel and oil
  • 5-layer silicone construction with heat-resistant embedded fibers for high-pressure durability
  • Hump-style design allows for increased flexibility to compensate for engine vibration and chassis flex
  • Ideal for custom intercooler piping kits and high-performance forced induction builds
  • Manufacturer Part Number: MMDCC-40HBK
  • Inlet/Outlet Diameter: 4.0 inches
