2016 370Z Sport Dealer no help with oil cooler

newpanama

I just bought a 2016 370Z Sport Coupe a couple weeks ago. As several threads that exist already talk about engine oil temps running hot and I have seen it myself. I would like to purchase the NISMO Oil Cooler Part Number: 21300-SS370 that was mentioned various times. My dealer seems to be unable to find the part for this. Any help on where I can get the geniune Nissan part which is what I prefer as well as recommendations on a dealership or someone in the Indy area trustworthy to install it would be greatly appreciated? My current dealer's service department isn't boosting my confidence in their doing it as they seem to have never done this install before or be able to find the part. Thankful for any help or guidance anyone can give.
