* Cylinder heads with heater hose fitting besides the header
* The tread on the head is M20x1.0
Some of you may be interested in deleting the heater hoses and heater core from your K-swapped vehicle. The K-Tuned Heater outlet plug is made from zinc plated steel and allows removal of the OEM heater hose fitting found on the exhaust side on some K-series cylinder heads. For installation, simply remove the OEM pipe fitting and replace it with our K-Tuned plug for a nice clean look. The plug comes with a new crush washer to prevent any coolant leaks. Ugly looped heater hoses are no longer needed.
