So it seems my stock oil cooler has seen better days, my end goal for this car is to end between 500 and 600hp. Anyone have recommendations for an oil cooler my car can grow into that is inexpensive? (I saw a couple on mafperfoance for over 1k and cried especially when it seems to be working fine but it bothers me knowing there is something wrong there).

Bent, no leaks.

Mishimoto makes oil coolers under $600. I'm sure a vendor here would help get that price lower.

I'm pretty sure AMS makes one, and they use the best cooler on the market, Setrab.
