Description
The Mishimoto DuraCoreâ„¢ 90-Degree Silicone Intercooler Boot (MMDCC-30A9BK) is a black, angle-configured coupler purpose-built for fabricators assembling a custom intercooler piping kit. Molded from five layers of silicone reinforced with heat-resistant embedded fibers, this 90-degree boot is designed to be the strongest link in your charge-piping system rather than the point where it fails.
At the core of every Mishimoto silicone boot is DuraCoreâ„¢ technology, a synthetic innermost layer that delivers superior resistance to heat, pressure, fuel, and oil compared to standard silicone. That added resistance helps prevent leaks and blowouts under high-boost conditions, making this boot a dependable choice for anyone building out a serious air intake system or intercooler piping setup. Reinforcing rings add structural integrity at connection points to keep the seal secure under pressure, and the boot is coolant compatible for added versatility in your build. As part of Mishimoto’s broader DuraCoreâ„¢ lineup of air intake systems components, this 90-degree boot is available alongside straight, straight hump, transition, and 45-degree configurations in sizing from 3″ to 4″, so your piping kit doesn’t have to compromise on layout.
Vehicle Applications
This DuraCoreâ„¢ 90-Degree Silicone Intercooler Boot is a universal-fit component intended for custom intercooler piping fabrication rather than a single factory application. It’s designed to help you route charge pipes around tight engine bays or connect mismatched tube diameters on custom builds, giving fabricators the flexibility to complete a piping kit to their own specifications.
