The stock radiator is very expensive to replace and fails after some miles as it has plastic end tanks. When we were looking for one is was ridiculous that used ones go for $300 and brand new one from the dealer is nearly $1000. So we wanted to make one since we have had great success making upgraded ones for the other vehicles we specialize in. The tricky part is we couldn't make it bigger like our other vehicles because it has to fit into the factory radiator housing, so we made it full aluminum including the end tanks for better efficiency keeping it the same size so it bolts up into the factory plastic housing shroud. We've been testing this unit for nearly 2 years before we decided to sell it to the public. We not only make a brand new unit much cheaper than the factory original one, but we also made it a higher quality, more efficient radiator at a better price tag. Used ones are too risky as most of them are from crashed cars and who wants to do all the labor and take it all apart again. This fits all 2016 to 2020 Tesla Model S vehicles.
