I am looking to do custom lines instead of the OEM hard lines. I just can't seem to find what thread pitch and size goes into the oil cooler so I can buy the fittings.

I think it's M18 x 1.5 but I'm not positive.

Thanks!

that is where you can get everything you need. ive done this exact thing already. attached is my invoice. order that list exactly and you will have all that you need to replace the hard lines and the stock fittings.
