Description
The Mishimoto DuraCore Silicone Straight Intercooler Boot (MMDCC-35SBK) is a black, 3.5-inch straight silicone coupler purpose-built for custom intercooler piping systems. Constructed from five layers of silicone reinforced with heat-resistant embedded fibers, this boot uses Mishimoto’s DuraCore technology in its innermost layer to stand up to heat, pressure, fuel, and oil exposure that standard silicone couplers struggle to survive under sustained high-boost conditions.
As part of Mishimoto’s broader DuraCore intercooler boot lineup, this coupler shares a family of options that includes straight, straight hump, transition, 45-degree, and 90-degree configurations spanning 3 to 4 inches in sizing, so builders can find the exact size and shape their fabrication demands for a complete air intake system or intercooler piping kit. Whether you’re routing charge pipes through a tight engine bay or replacing a failure-prone factory coupler, this Mishimoto boot is engineered to be the strongest link in the build rather than the point where it lets you down, and it remains coolant compatible for added versatility in a piping layout.
Vehicle Applications
This DuraCore Silicone Straight Intercooler Boot is a universal-fit component rather than a vehicle-specific part. It’s designed for fabricators and builders routing custom intercooler piping around tight engine bays or connecting mismatched tube diameters, giving you a coupler size and shape suited to whatever fabrication project you’re working on, independent of make, model, or year.
