Mishimoto MMDCC-30SBK DuraCore 3-Inch Straight Silicone Intercooler Coupler Boot Black

The Mishimoto MMDCC-30SBK DuraCore 3" Straight Silicone Intercooler Boot is a premium-grade silicone coupler engineered for custom intercooler and charge piping fabrication. Designed to be the strongest link in your intercooler piping kit, this straight boot delivers a secure, leak-resistant connection in demanding high-boost applications.

DuraCore™ Technology:

At the heart of this coupler is Mishimoto's proprietary DuraCore™ synthetic inner layer — a material engineered to outperform standard silicone in every critical area. Compared to conventional silicone couplers, DuraCore™ delivers superior resistance to heat, pressure, fuel, and oil, effectively extending boot life by preventing leaks and blowouts under high-boost conditions.

Key Features:

• 3-inch straight configuration — ideal for inline connections in custom intercooler and intake piping setups
• Five-layer silicone construction with heat-resistant embedded fibers for maximum structural integrity
• DuraCore™ synthetic inner layer resists heat, pressure, fuel, and oil better than standard silicone
• Reinforcing rings add structural rigidity to keep connections secure under elevated boost pressure
• Tight, leak-resistant seal engineered to handle the demands of street and track performance builds
• Sleek black finish for a clean, professional appearance in any engine bay
• Part of the full DuraCore™ lineup, available in straight, straight hump, transition, 45-degree, and 90-degree configurations in 3" to 4" sizing
• Backed by Mishimoto's Lifetime Warranty

Whether you're routing charge pipes through tight engine bays or connecting sections of a custom intercooler system, the MMDCC-30SBK provides the reliability and performance your build demands. Pair it with other DuraCore™ boots and Mishimoto clamps for a complete, cohesive piping solution.
