Mishimoto MMDCC-35A9BK DuraCore 3.5in 90-Degree Silicone Intercooler Boot Black

Vehicle Fitment

• Universal fit - compatible with any custom intercooler piping, charge pipe, or turbo system requiring a 3.5" inside diameter 90-degree silicone boot

Fitment Notes

• Inside Diameter: 3.5 in. (88.9mm) on both ends - verify your intercooler or charge pipe OD before ordering
• 90-degree geometry allows charge pipes to make a full right-angle turn in confined or complex engine bay layouts
• Designed for intercooler piping, charge pipe, and turbo inlet/outlet connections in custom builds
• Hose clamps are not included - use appropriately sized T-bolt or worm-gear clamps on each end
• Available in black (BK), blue (BL), and red (RD) - this listing is for the black version
• Part of the full Mishimoto DuraCore™ boot lineup: available in straight, straight hump, transition, 45-degree, and 90-degree configurations in 3" to 4" sizing

Features

• DuraCore™ synthetic inner layer provides superior resistance to heat, pressure, fuel, and oil versus standard silicone
• Five-layer silicone construction with heat-resistant embedded fibers delivers maximum structural integrity
• 90-degree bend enables full right-angle charge pipe routing around engine bay obstacles and tight corners
• Reinforcing rings at connection points lock the boot rigid under high boost to prevent blowouts
• Engineered for intercooler and charge pipe builds - withstands oil and fuel exposure in high-boost diesel and gas applications
• Black finish provides a clean, professional underhood appearance
• Backed by the Mishimoto Lifetime Warranty

Product Description

The Mishimoto MMDCC-35A9BK is a 3.5-inch 90-degree DuraCore™ silicone intercooler boot built for custom charge pipe and intercooler piping layouts that require a full right-angle change of direction. The 90-degree profile is the most common geometry in diesel and performance gas intercooler builds, where charge pipes must navigate around radiators, engine blocks, or structural members before connecting to the intercooler core or throttle body.

DuraCore™ technology lines the innermost layer with a synthetic material specifically engineered to resist heat, pressure, fuel, and oil - the conditions that degrade standard silicone boots in high-boost applications. Five silicone layers reinforced with heat-resistant embedded fibers and reinforcing rings at each clamping zone provide the structural integrity to hold under sustained boost without ballooning or blowing out. Clamps are sold separately - T-bolt clamps are recommended for high-boost builds. Backed by the Mishimoto Lifetime Warranty.
