Application: K24Z-Series heads - 2012-15 Civic Si / 2009+ Acura TSX
K-Tuned is known for its innovative and popular cooling components for k-series applications. We've continued this k-series support with now the upper coolant housing for the K24Z-Series/R40 style head. The upper coolant housing features interchangeable coolant fittings (standard silicone hose / -12AN / -16AN). The plate is tapped to use the standard coolant temp sensor as well as a 1/8 NPT port that can be used for swap cars temp sensors or other with similar threads. Heater hose adapters are included as well as a plug those wanting to delete heat in the car. The adapter seals with an o-ring to ensure quick and easy installation.
