Great Product !
Very easy to install, comes with everything you need which is nice. I added the extra plug for the lower line which was worth it. Seems to work very well but I have yet to put many miles on the car.

E36 Heater Delete
This blank off plate fit perfectly and is robust enough to hold back coolant pressures. Installed as part of a heater bypass mod for my E36 track car. Drove Road Atlanta hard for two days in July! No leaks. Installed with provided gasket only, no additional sealer as I intend to convert back each winter. Good product.
