Aluminium Thermostat Housing FMIC.EU for Honda K20Z3 K24 16 ORB CNC

Aluminium Thermostat Housing FMIC.EU for Honda K20Z3 K24 16 ORB CNC

The FMIC.EU upper coolant housing is a precision CNC-machined aluminum replacement for the OEM part, designed for Honda K-Series engines. Developed for turbo builds, engine swaps, and track applications, it solves the common issue of upper radiator hose interference with intake systems or turbo manifolds.

The adjustable hose outlet allows approximately 15° of angle adjustment, enabling precise radiator hose routing and improved clearance, especially important in sidewinder and big turbo setups.
The housing features a -16 OR (O-Ring) outlet and a -12 OR (O-Ring) filler neck inlet. It supports either a traditional 1.25” rubber/silicone hose or conversion to AN fittings.

An optional filler neck allows relocation of the radiator cap to the highest point of the cooling system, significantly improving bleeding efficiency and eliminating air pocket issues.

Manufactured from high-quality aluminum, resistant to heat and pressure, ensuring durability in motorsport and high-performance applications.
