K Series engine aluminium alloy intake manifold coolant adapter for Honda K20 K24 engines, compatible with aftermarket cooling system modifications, one complete fitting set
Aluminium alloy K Series intake manifold coolant adapter for Honda K20 K24 engine modifications

This aluminium alloy coolant adapter provides a replacement connection point for the intake manifold on Honda K Series engines, specifically designed for K20 and K24 applications. It enables modification of standard cooling system routing when installing aftermarket components or creating custom coolant setups. The adapter comes as a complete fitting set with all necessary components in one package, eliminating the need to source multiple parts separately. With dimensions of 145mm x 105mm x 35mm and weighing 0.316kg, this adapter offers a direct replacement option for factory intake manifold coolant connections.
Features and Construction

The K Series coolant adapter features aluminium alloy construction designed specifically for engine bay environments. This material selection provides corrosion resistance while maintaining dimensional stability under temperature variations common in automotive applications. The adapter is manufactured to precise specifications for compatibility with K Series intake manifold mounting points.
Material and Build
Constructed from aluminium alloy, this adapter utilises a material that balances strength with weight considerations in engine applications. The alloy composition provides resistance to corrosion from coolant exposure while maintaining integrity under engine bay temperature conditions. The manufacturing process ensures precise dimensions for proper fitment without requiring modification of existing intake manifold surfaces.
Size and Practical Fit
With dimensions measuring 145mm x 105mm x 35mm, the adapter is designed to integrate with K Series intake manifold dimensions while providing sufficient material for secure mounting. The 0.316kg weight contributes to minimal added mass in the engine compartment. These measurements ensure the adapter fits within typical K Series engine bay space constraints while providing adequate material for proper sealing surfaces.
Uses and Placement

This adapter serves as a connection point between the intake manifold and cooling system components on modified Honda engines. It facilitates alterations to standard coolant routing when installing aftermarket radiators, expansion tanks, or custom cooling setups. The adapter enables integration of non-standard cooling system components while maintaining proper connection to the intake manifold.
Event or Professional Use
For motorsport applications or professional builds, this adapter allows custom cooling system configurations on competition or high-performance K Series engines. It provides a reliable connection point when standard coolant routing requires modification for specific racing classes or dyno testing setups. The complete fitting set approach ensures all necessary components are available for professional installation without additional sourcing.
Everyday Home Use
For enthusiast builds and modified road vehicles, this adapter enables cooling system upgrades on street-driven K Series engines. It facilitates installation of aftermarket cooling components while maintaining proper manifold connections. The single package containing all necessary fittings simplifies the modification process for home mechanics undertaking cooling system improvements.
