Unless your going to race/ rally etc etc the car you dont,t need a 10 or 13 row oil cooler
One like this is much better

contrary to what I posted in that thread about the thermostat , it would be much better to have it set up that the oil only only flows into the cooler once it reaches a certain temperature or it will clog very quickly , yes you can remove it and flush with kero but you don,t want to be doing it all the time
