What's the pitch/thread of the oil filter stud?
 

I'm trying to shop for an aftermarket oil cooler kit, but I need to know what the pitch/thread of the oil filter stud is, so that I order the proper sandwich adapter.

just pick up a stock 280zxt oil cooler plate and have your local machine shop try and port it out a little.

for once im gonna be an ass because we talked about this not too long ago...but its in the search...scroll down to my post
10th post down...at least on the canadian model it is lol

Sweet, thanks!

not a problem.
exact numbers i have ordered, I think the oil cooler is overkill but oh well
EAR-510ERL
BMM-70264

no such thing as overkill when it comes to your engine. Its just being precautious ;) Neon windshield squirters are overkill :p
