Fabricate your custom intercooler system with confidence using the Mishimoto DuraCore 3-inch 45-degree silicone coupler. Engineered as a high-strength link for charge pipe assemblies, this boot is designed to withstand the extreme pressures and temperatures found in high-performance and heavy-duty truck builds.

The defining feature of this coupler is DuraCore technology—a specialized synthetic material forming the innermost layer. This lining provides significantly higher resistance to fuel, oil, and heat compared to standard silicone, effectively preventing the degradation that leads to leaks and blowouts under high-boost conditions. Each boot features a robust 5-ply construction with heat-resistant embedded fibers for maximum structural integrity under load.

  • Construction: 5-Ply Silicone with heat-resistant embedded fibers
  • Technology: DuraCore inner liner for superior oil and fuel resistance
