Is there? I dont think there is but a friend of mine said its good for any engine regardless of what mods you have done.

 

Heat causes wear, therefore, less heat = less wear. It's not necessary, but a good idea...

 

it is beneficial. stock rd tibs run hotter than they should by like 10 or 15 degrees and a oil cooler would help in the life of components

 

to play devils advocate against this idea.. for those in cooler areas. Oil needs to get up to temp to function properly. In areas (not mine) that get freaking cold the cooler would keep it thicker for much longer. Maybe a valve to shut it off during the winter as a few did with the TB coolant "mod"?
