KPower K24A2 Upper Coolant Neck - 1.25' Barbed

If you’re familiar with the K series heads, you know that once you rotate the engine to fit in the Miata bay, the upper coolant neck sticks straight into the firewall. While there are other products on the market that allow you to redirect the neck parallel to the firewall, KPower created the perfect solution specifically for the KMiata swap.

This piece replaces the bulky fitting on the head, and re-uses the OEM gasket. It includes a port for the heater hose and optional plug for race cars. It also includes a port specifically for your stock Miata coolant temperature sender, which allows the factory Miata gauge to operate without any modification. A ?” NPT port is also included, with optional plug, so any aftermarket gauge sender can be used.
