Here is a custom made main radiator. It's from another world than the OEM one. Based on high quality German made core. All kind of cooling problems solved after some other radiator replacings and adding s spoilers under the car to bring airflow to the main radiator.

 

I saw that but, since they do not say "UK made" and "hand made" like what Powerhouse state, I thought it was some other model and, because it is cheaper and as they are silent about the country of manufacture, I could not exclude the possibility that it is China made. Thus I did not provide the link to it. Having now had another good look at the picture, I think it is the same as what I bought, i.e. UK made.
