Mishimoto MMDCC-35A4BK DuraCore 3.5in 45-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 45-degree silicone boot

Fitment Notes

• Inside Diameter: 3.5 in. (88.9mm) on both ends - verify your intercooler or charge pipe OD before ordering
• 45-degree geometry routes charge pipes cleanly around obstructions in tight or angled 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
• 45-degree bend allows clean charge pipe routing in confined engine bays where straight boots won't clear
• 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-35A4BK is a 3.5-inch 45-degree DuraCore™ silicone intercooler boot built for custom charge pipe and intercooler piping layouts that require a directional change without a full 90-degree turn. The 45-degree angle is ideal for routing around components in congested engine bays where a straight boot can't clear and a 90-degree boot would be too aggressive - giving fabricators precise control over pipe routing geometry.

DuraCore™ technology lines the innermost layer with a synthetic material specifically engineered to resist heat, pressure, fuel, and oil - the conditions that cause standard silicone boots to blister, swell, and fail prematurely in high-boost applications. Five silicone layers reinforced with heat-resistant fibers and reinforcing rings at each clamping zone deliver the structural rigidity 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.
