Description
The Mishimoto DuraCore™ MMDCC-30A4BK is a 45-degree black silicone intercooler boot purpose-built for custom charge-piping fabrication, featuring Mishimoto’s proprietary DuraCore™ synthetic inner layer for added durability under boost. Measuring 3.43 inches in outer diameter and 5.93 inches in overall length, this angled coupler is shaped to route intercooler piping through tight engine bay geometry without kinking or restricting flow.
As part of Mishimoto’s air intake systems lineup, this DuraCore™ boot is built to be the strongest link in a custom intercooler piping kit. The DuraCore™ synthetic layer resists heat, pressure, fuel, and oil better than standard silicone alone, helping extend boot life and prevent leaks or blowouts under high-boost conditions. Each boot is constructed from five layers of silicone with heat-resistant embedded fibers, and reinforcing rings add structural integrity at connection points where boost pressure is highest. Whether you’re building an entirely new air intake system or replacing a failure-prone section of your existing piping, this 45-degree boot gives fabricators a durable, secure transition point.
Vehicle Applications
Because this DuraCore™ boot is engineered as a universal fabrication component rather than a vehicle-specific part, it’s intended for custom intercooler piping kits on turbocharged builds where a 45-degree silicone transition is required. It’s designed to pair with Mishimoto’s broader DuraCore™ range of straight, straight hump, transition, and 90-degree boots, sized from 3″ to 4″, so fabricators can complete a full custom piping route to match any engine bay layout without being locked into a single make or model.
