Mishimoto MMDCC-30HBK DuraCore 3.0in Straight Hump Silicone Intercooler Boot BK

Vehicle Fitment

• Universal fit - compatible with any custom intercooler piping, charge pipe, or turbo system requiring a 3.0" inside diameter straight hump silicone boot

Fitment Notes

• Inside Diameter: 3.0 in. on both ends - verify your intercooler or charge pipe OD before ordering
• Straight hump design absorbs vibration, movement, and thermal expansion in-line without redirecting flow
• Ideal for charge pipe connections where slight axial misalignment or component movement is expected
• Hose clamps are not included - use appropriately sized T-bolt or worm-gear clamps for a secure, leak-free seal
• 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
• Hump profile absorbs vibration and movement, protecting the piping connection from fatigue and seal failure
• Reinforcing rings at connection points lock the boot rigid at clamping zones to eliminate 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 appearance in the engine bay
• Backed by the Mishimoto Lifetime Warranty

Product Description

The Mishimoto MMDCC-30HBK is a 3.0-inch straight hump DuraCore™ silicone intercooler boot designed for custom charge pipe and intercooler builds that require in-line flexibility without a change in direction or diameter. The hump profile is engineered to absorb vibration, thermal expansion, and minor axial movement between connected components - reducing stress on couplings and preventing the fatigue-related seal failures that flat straight boots are prone to in high-vibration environments.

Like all Mishimoto DuraCore™ boots, this coupler is built from five layers of silicone reinforced with heat-resistant embedded fibers, with DuraCore™ synthetic lining the innermost layer for enhanced resistance to heat, pressure, fuel, and oil. Reinforcing rings at each clamping zone prevent the boot from ballooning or blowing out under sustained boost. Clamps are sold separately - T-bolt clamps are recommended for high-boost applications. Backed by the Mishimoto Lifetime Warranty.
