Description

The Mishimoto DuraCore 4-Inch 90-Degree Silicone Intercooler Coupler is engineered to provide a dependable connection for custom intercooler, intake, and charge-pipe systems. Part number MMDCC-40A9BK helps route piping through tight engine bays while maintaining a secure, leak-resistant seal. Its 90-degree configuration is ideal for fabrication projects that require a controlled change in direction without sacrificing connection strength or system reliability.
Mishimoto DuraCore technology forms the innermost layer of this silicone coupler, delivering improved resistance to heat, pressure, fuel, and oil compared with standard silicone. The coupler is constructed from five layers of silicone reinforced with heat-resistant fibers, helping prevent leaks, blowouts, and premature wear during high-boost operation. Its robust construction is suitable for demanding automotive applications where dependable charge-air connections are essential.
Designed for custom piping kits, the Mishimoto DuraCore coupler provides installation flexibility while accommodating movement and vibration within the system. Reinforcing rings, where applicable, add structural integrity and help maintain a secure connection under pressure. Pair it with properly sized clamps and compatible piping to create a durable intercooler or intake assembly. Mishimoto offers matching straight, hump, transition, 45-degree, and 90-degree configurations in multiple sizes for a complete, application-specific build.
