There are definitely other suppliers making radiators for our cars; rockauto shows 7 different aftermarket brands available from as cheap as $83.89 with an average price point of just over $100. I'm not sure that any of the aftermarket ones have improved the performance in any way (though there are certainly intercoolers to be had to accomplish that, hah), but with the OEM radiator costing just over $200, I plan on going with a cheaper supplier should I indeed need to replace my radiator and putting the savings towards a set of silicone coolant hoses... god knows the ones in my 140k-mile 2014 have seen better days (;^ω^)
