K24A2 Upper Coolant Neck

The KMiata upper coolant neck for the K24A2 head is the ultimate solution for your K swap plumbing needs.

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, we’ve 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 ⅛” NPT port is also included, with optional plug, so any aftermarket gauge sender can be used.

Depending on your preference, we’ll include a 1.25” barbed radiator hose fitting, or a -16 AN fitting, so you can build the rest of your cooling setup any way you’d like.
