Hey guys!

So I have got a TD04h with me, I am not 100% sure what car it's off but the serial code is 49189 - 00640 070310015.

I was wondering what oil fitting sizes would i need?

I was looking at -3an or -4an?
Do I need to have a restrictor? Previous owner said he had 2mm restrictor but his oil light came on, I would assume that pressure is low?
I believe I need to be running at least -10an for the oil drain?

Thanks guys
