thermostat jammed and overheating cracked my fancy aluminum radiator. so now for something new. looking for top of the line aftermarket or a good place to source oem. 01 sport manual, tips are appreciated. thanks for your time
 
Yes, OEM is still the best. However, good luck on finding one. eBay would be your best bet because at this point all it's going to be is leftover stock if you can find one at all.

One year in and the Koyorad is still working fine . Rode some trails in the Arkansas mountains last Tuesday in 102 degree temperatures with the ac on and it ran normal operating temperatures .

Drove around town last week in stop and go traffic with a 106 outdoor temperature and the coolant stayed in the normal range right at 210 .

Last time I checked mrblaine had a few but may not be worth it with shipping and all. He may not even want to get rid of the few he has. I went Mishimotot but hasn't been in long enough to judge longevity but it did really well in Moab this past July. The Mishimoto is a 2 core set up for around 450. AFE makes one that is a 3 core for around 550 and they are direct replacements. Lots of people have had success with local auto parts stuff I just HATE plastic pans.
 
My original OEM lasted 20 years. I replaced it with another Mopar unit, unfortunately just had to replace it after 6 years due to leaking at the seams a considerable amount.

Wasn’t able to find another mopar for a reasonable price so I bought a denso. I guess we’ll see how that goes but my experience with replacement mopar was not good enough to justify the hunt and price for one.
