Is your K swapped Miata primarily and track car or race car? Clean up your engine bay and eliminate unwanted weight and clutter with the Hybrid Racing heater delete kit.

This kit allows you to delete the heater hoses running from the engine block and cylinder head to the heater core behind your dashboard.  

If you have a K20A2 or K20Z1 style head, order with the head plug pictured. If using a K24A2 style head, the head plug is not needed. Just use the 1/2" NPT plug that comes with our K24 Upper Water Neck.
