Straight Inlet Upper Coolant Housing

The K-Tuned K24/K20Z3 Straight Inlet Upper Coolant Housing is engineered for K20Z3 and K24 engine applications, providing distinct advantages over stock units. Its primary feature is a hose outlet that pivots up to 15 degrees, offering improved clearance compared to fixed factory outlets that often conflict with intake piping. This housing is equipped with a standard 1.25" radiator hose outlet, a -16OR outlet, and a -12OR filler inlet. Optional 16AN fittings are available for advanced setups. Additionally, an optional Filler Neck can be added to relocate the radiator cap to the highest point of the cooling system, facilitating easier air pocket escape during the coolant bleeding process. The optional Filler Neck is compatible with an OEM 92-00 Honda Civic radiator cap. It is important to note that this housing excludes K24A1, K24Z, and K24Y series engines. There may also be fitment issues with Jackson Racing Superchargers when using the K20 Upper coolant housing. A radiator cap is not included and must be purchased separately.
