Does anyone know what the correct Inlet/Outlet size for the stock Oil cooler is? I'm considering an aftermarket oil cooler and many of them seem to be 3/8" NPT. I appologize if I missed an obivous previous post, but I did search.

 

Snrub, The stock FC Oil Cooler is one of the biggest and most efficient available. Barely nothing aftermarket comes even remtely close with the exception of a few high priced custom Oil Coolers.

 

Thanks for the reply. Perma-cool makes a lot of different coolers that are bigger. For instance they make one that's six pass 20"x11.5"x1.5". That's like 80% of the stock rad. Another is 21x10.5"x4". Comments, suggestions?

 

Hmm...not to deter you on getting an aftermarket Oil Cooler, I say you take yours out and have It machined cleaned. It'll turn out like new and you'll still save a ton, should you decide to go with this.

 

The thing is there is nothing inherently wrong with the oil cooler (that I'm aware of). I simply need more cooling.
