The Mishimoto DuraCore 3-Inch 90-Degree Silicone Intercooler Coupler, part number MMDCC-30A9BK, is designed to create a secure connection between charge pipes in custom intercooler, turbocharger, and intake systems. Its 90-degree configuration helps route piping around tight engine bays while maintaining a reliable, leak-resistant seal. The coupler is suitable for fabrication projects and replacement applications where dependable high-boost performance is required.
Mishimoto DuraCore technology uses a synthetic inner layer engineered to resist heat, pressure, fuel, and oil better than standard silicone. The coupler is constructed from five layers of silicone reinforced with heat-resistant embedded fibers, providing durability in demanding engine compartments. This layered design helps reduce the risk of leaks, blowouts, and premature wear when exposed to elevated temperatures and pressurized intake air.
The 3-inch coupler is engineered to connect compatible intercooler or charge-pipe tubing and can be secured with appropriately sized clamps. Its flexible silicone construction supports easier installation while helping accommodate normal movement and vibration within the piping system. As part of Mishimoto’s DuraCore lineup, this coupler is available alongside straight, hump, transition, 45-degree, and other 90-degree configurations to support a wide range of custom piping layouts. Professional installation and properly matched tubing and clamps are recommended for the best seal and long-term performance.
