Reinforced Silicone Construction
Mishimoto constructs these hoses from high-grade silicone reinforced with embedded heat-resistant fibers.
The layered construction helps the hoses retain their shape through repeated heating and cooling cycles. It also provides increased pressure tolerance compared with old factory rubber hoses that may have softened, swollen or begun separating internally.
Published specifications include:
- Maximum temperature: 330°F
- Listed inner diameter: 1.18 inches
- Listed outer diameter: 1.54 inches
- Material: Reinforced silicone
- Color: Black
- Manufacturer part number: MMHOSE-INT-94BK
The diameter figures are manufacturer-listed specifications and should not be interpreted as measurements applying uniformly across every molded section.

Why Replace Integra Radiator Hoses?
Radiator hoses operate under heat and pressure every time the engine reaches operating temperature. Years of coolant exposure and engine movement can cause factory rubber hoses to deteriorate internally and externally.
Warning signs include:
- Cracks around the hose ends
- Soft or swollen sections
- Coolant residue around a clamp
- A hose that feels unusually hard
- Oil contamination
- Abrasion against nearby components
- Coolant odor after driving
- Unexplained coolant loss
- Engine-temperature fluctuations
- Internal hose collapse
A hose can appear acceptable while its inner lining is already separating. Waiting until coolant reaches the pavement is technically one inspection method, although not a particularly sophisticated one.
Black Silicone Maintains an OEM-Plus Appearance
The black finish makes this kit appropriate for owners who want improved hose construction without adding a bright color to the engine compartment.
It works particularly well with:
- Factory restorations
- OEM-plus street builds
- Naturally aspirated B18 engines
- Turbocharged B-series builds
- Upgraded aluminum radiators
- Track and autocross cars
The understated appearance also keeps attention on the engine rather than making the radiator hoses the visual centerpiece of the entire build.
Installation Overview
Never remove a radiator cap or coolant hose while the engine is hot. A pressurized cooling system can release boiling coolant and steam without warning.
Basic installation steps include:
- Allow the engine to cool completely.
- Place a suitable drain pan beneath the radiator.
- Remove the radiator cap only when the system is cold.
- Drain the existing coolant.
- Remove the original upper and lower radiator hoses.
- Inspect the radiator necks and engine connections.
- Clean corrosion and old coolant residue from each fitting.
- Compare the new hoses with the original routing.
- Install each hose without twisting or stretching it.
- Position the clamps behind the raised beads on the fittings.
- Refill the system with the correct coolant mixture.
- Bleed trapped air from the cooling system.
- Bring the engine to operating temperature.
- Check every connection for leakage.
Recheck the coolant level after the engine cools. Inspect clamp position again after several complete heat cycles.
Inspect the Entire B-Series Cooling System
Radiator hoses are only part of the cooling system. While the coolant is drained, inspect:
- Radiator tanks and necks
- Radiator cap
- Thermostat and housing
- Water pump
- Cooling fan and fan switch
- Heater hoses
- Coolant reservoir
- Cylinder-head water outlet
- Coolant temperature sensors
- Timing belt and water-pump service history
Overheating can warp the aluminum B-series cylinder head and compromise the head-gasket seal. Our guide explaining how to repair a B18 blown head gasket covers the considerably more expensive outcome of ignoring a cooling-system problem.
Will This Kit Fit an Engine-Swapped Integra?
Not automatically.
B16, B18C, B20 and K-series swaps can use different water outlets, thermostat housings, radiators and hose routing. Turbocharger placement and aftermarket intake manifolds may also affect clearance.
Owners should inspect the installed configuration instead of ordering entirely by chassis year. The VIN may say Integra, but the engine bay may contain an entirely different interpretation of Honda engineering.
Measure the radiator connections and identify the engine before purchasing hoses for a swapped vehicle.
Why Choose the Mishimoto Integra Hose Kit?
The MMHOSE-INT-94BK provides a straightforward cooling-system refresh for most 1994–2001 Integra models.
Its reinforced silicone construction increases resistance to heat and pressure, while the black finish maintains a clean engine-bay appearance. It’s a practical choice for replacing deteriorated factory hoses during a radiator, thermostat or water-pump service.
