Description
The Mishimoto DuraCore™ Silicone Intercooler Boot, MPN MMDCC-3035BK, is a black straight-style transition coupler engineered for fabricators building custom intercooler piping kits. Constructed from five layers of silicone with heat-resistant embedded fibers and finished with the proprietary DuraCore™ synthetic inner layer, this boot is designed to be the strongest link in a high-boost piping system rather than its weak point.
As part of Mishimoto’s air intake system component lineup, this silicone intercooler boot exists to solve a specific fabrication problem: connecting mismatched tube diameters without sacrificing durability. Compared to standard silicone, the DuraCore™ layer delivers superior resistance to heat, pressure, fuel, and oil, which helps extend boot life and prevent leaks or blowouts under sustained high-boost conditions. Reinforcing rings add structural integrity where applicable, locking connection points rigid so the piping kit stays sealed under pressure. Available across straight, straight hump, transition, 45-degree, and 90-degree configurations from 3″ to 4″, this particular unit is a straight transition-style boot built to bridge differing pipe diameters cleanly in a custom air intake or intercooler piping layout.
Vehicle Applications
This DuraCore™ silicone intercooler boot is a universal fabrication component rather than a vehicle-specific part — no make, model, or year fitment is specified by Mishimoto for MMDCC-3035BK. It is intended for builders fabricating or upgrading a custom intercooler piping kit who need a boot sized to bridge a 3-inch to 3.5-inch diameter transition, making it suitable for whatever platform your custom charge-pipe or intercooler routing requires.
