Another oil cooler question

[Benquattro]

Hi,
I still don't understand..
My 3B original oil cooler needs to be replaced by a bigger one.

Is there any type of oil cooler I can just drop in?
The audi oil lines, do they fit any bigger type of oil cooler?
I'm confused with NPT, AN, 12L, m18x1.5 , ....
Just want to buy a bigger oil cooler and lines that fit.

rs2 oilcooler is bigger. What power are you running?
You can use a mocal cooler with AN fittings. Not drop in, but certainly better.

rs2 spec.
I'll try and score a rs2 oil cooler, don't understand the whole AN-thingie.
thanks
