Mishimoto MMDCC-35SBK DuraCore 3.5in Straight 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 straight silicone boot

Fitment Notes

• Inside Diameter: 3.5 in. (88.9mm) on both ends - verify your intercooler or charge pipe OD before ordering
• Straight profile - connects two pipes of the same diameter in-line with no change in direction or size
• 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
• Straight geometry provides a clean, direct connection between two 3.5" pipes in-line
• 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-35SBK is a 3.5-inch straight DuraCore™ silicone intercooler boot designed for custom charge pipe and intercooler builds where two 3.5" pipes need a direct, in-line silicone connection. The straight profile makes it the go-to choice for bridging pipe joints, connecting an intercooler to a charge pipe, or anywhere in a piping layout where no change in direction or diameter is required.

DuraCore™ technology lines the innermost layer with a synthetic material that resists heat, pressure, fuel, and oil better than standard silicone - the conditions present in high-boost diesel and gas applications where inferior boots crack, swell, and fail. Five silicone layers reinforced with heat-resistant embedded fibers and reinforcing rings at each clamping zone provide 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.
