Description
The Mishimoto DuraCoreâ„¢ Silicone Intercooler Boot (MMDCC-30SBK) is a straight-style black silicone coupler engineered for custom intercooler piping kits. Built with a 3.43-inch outer diameter and 3.5-inch overall length, this boot uses Mishimoto’s proprietary DuraCoreâ„¢ synthetic inner layer to stand up to the heat, pressure, fuel, and oil exposure that standard silicone can’t always handle. It’s a purpose-built component for fabricators who need a boot that won’t be the weak point in their build.
Whether you’re piecing together a custom air intake system, rerouting charge pipes around a tight engine bay, or connecting mismatched tube diameters in a turbo or intercooler setup, this DuraCore straight boot delivers a rock-solid connection point. Each boot is molded from five layers of silicone reinforced with heat-resistant embedded fibers, and reinforcing rings add structural integrity where applicable to keep connections locked down under boost. With a maximum temperature rating of 347°F and coolant compatibility, the MMDCC-30SBK is built to handle demanding truck and performance builds without leaking or blowing out under pressure.
Vehicle Applications
This DuraCoreâ„¢ silicone intercooler boot is a universal-fit component rather than a vehicle-specific part—it’s designed to complete custom intercooler and turbo piping kits on trucks and performance builds where fabricators need a straight coupler sized to match their piping. Because it’s part of Mishimoto’s full DuraCore lineup, which spans straight, straight hump, transition, 45-degree, and 90-degree configurations from 3 inches to 4 inches, it can be paired with straight tubing of matching diameter on virtually any custom-built intake or intercooler piping system, regardless of make or model.
