Description
The Mishimoto DuraCore™ 90-Degree Silicone Intercooler Boot (MMDCC-40A9BK) is a black, angle-shaped coupler purpose-built for fabricators assembling a custom intercooler piping kit. Molded from five layers of silicone with heat-resistant embedded fibers and finished with DuraCore™ technology on its innermost layer, this boot is engineered to be the strongest link in your charge-piping system rather than its weak point.
As part of Mishimoto’s broader air intake system lineup, this 90-degree coupler gives fabricators the flexibility to route charge pipes through tight engine bays without sacrificing sealing integrity. DuraCore™ technology delivers greater resistance to heat, pressure, fuel, and oil than standard silicone alone, which helps prevent leaks and blowouts in high-boost applications. Reinforcing rings add structural rigidity at the connection points, keeping the seal locked down under pressure, while the coupler itself is coolant compatible for added versatility in your air intake system build. Available across Mishimoto’s full DuraCore™ lineup in straight, straight hump, transition, 45-degree, and 90-degree configurations from 3″ to 4″, this particular boot lets you dial in the exact angle your piping layout requires.
Vehicle Applications
This DuraCore™ 90-degree silicone intercooler boot is a universal fabrication component rather than a vehicle-specific bolt-on part, making it suited to any truck build or custom intercooler piping project where a 90-degree transition is needed. Because it is not tied to a single make or model, it works alongside whatever mismatched tube diameters or tight-clearance routing your particular air intake system design calls for.
