Engine coolant adapter for K series intake manifolds on K20 and K24 Honda engines, designed for engine cooling system modifications with one adapter set per unit, measuring 145mm by 105mm by 35mm with a unit weight of 0.316kg.
K Series Intake Manifold Coolant Adapter for Honda K20 and K24 Engine Modifications

This adapter is engineered for the Honda K series engine platform, specifically the K20 and K24 variants. It serves as a dedicated component for modifying the engine's cooling system routing at the intake manifold. The product is supplied as one complete set, providing all necessary parts for a single installation. With precise dimensions of 145mm by 105mm by 35mm and a weight of 0.316kg, it is designed for direct application in performance tuning, cooling system upgrades, or specific engine bay layout projects where coolant line rerouting is required.
Features and Construction

The adapter's primary function is to interface between the K series intake manifold and the engine's cooling system hoses. Its construction is focused on providing a secure and leak-free connection point for modified coolant pathways.
Material and Build
While the specific alloy or composite material is not detailed in the source, the part is manufactured to fulfil the role of a coolant system adapter. This requires material properties capable of withstanding engine coolant temperatures and pressures. The design likely incorporates inlet and outlet ports sized for standard coolant hose diameters, and mounting points compatible with the intake manifold's existing fittings.
Size and Practical Fit
The adapter's external dimensions are 145mm in length, 105mm in width, and 35mm in height. These measurements are crucial for determining fitment within the often-crowded engine bay of Honda vehicles equipped with K20 or K24 engines. The 0.316kg unit weight indicates a relatively compact and lightweight component, which helps minimise added mass and simplifies handling during the installation process.
Uses and Placement

This component finds its application in various automotive modification scenarios centred around the K series engine. Its use is technical and targeted, appealing to those with specific mechanical goals for their vehicle's cooling system.
Event or Professional Use
For track-focused builds, time-attack vehicles, or professionally tuned engines, optimising coolant flow can be a consideration. This adapter allows for the creation of custom coolant routing, which could be part of a larger system designed to manage heat more effectively under sustained high-load conditions. It enables mechanics and tuners to implement bespoke cooling solutions that may not be possible with the factory manifold configuration.
Everyday Home Use
For the enthusiast working on their own vehicle, this adapter facilitates cooling system upgrades or repairs that involve rerouting hoses. It can be used when installing an aftermarket intake manifold that lacks the standard coolant ports, or when simplifying factory coolant lines for a cleaner engine bay aesthetic. It provides a solution for connecting coolant lines where the original routing is being altered.
Benefits and Buying Value

The value of this component lies in its specificity and functionality. It addresses a clear mechanical need within a popular engine modification platform.
Reuse and Low Maintenance
As a metal or composite hardware component, the adapter is designed for a single, permanent installation. Once fitted correctly with proper seals, it should not require routine maintenance outside of the vehicle's standard coolant system service intervals. Its value is realised through its ongoing function within the modified cooling system for the life of the installation.
Why Choose This Product
This product is chosen for its direct application to Honda K20 and K24 engines. The confirmed dimensions and single-unit packaging provide clarity for purchasers. It eliminates the need for custom fabrication of a similar part, saving time and potential inaccuracies. For anyone needing to alter coolant routing on these specific engines, this adapter offers a ready-made solution with known specifications.
