Oil cooler lines

[Lofty]

I'm running stainless braided lines for my aftermarket oil cooler.

I've seen in a Mavisky writeup, he used -6 AN

I've been told always go with -8 AN but I already bought -6, but I should be fine.

Will I see any issues?

You'll be fine. I'm running -10 AN and I don't have any issues.

Jon91TSi 10an is larger than 8an. So yes you wont have any problems...
But 6an seems a bit small, you dont want a restriction in the oil system preventing the flow of oil.
Im not sure what the inside diameter of the stock oil lines are, but I would measure the stock lines and not go smaller...
If thay are smaller than 6/16th than 6an will be fine.

Oops, completely read his post wrong, I thought he said he saw the writeup that called for -6AN, but used -8AN. My apologies. You will be fine with -6, as you are still moving plenty of volume though the lines. I have quite a few friends running -6 lines on B&M coolers and they have been set up this way for years without problems.

Problem solved then
I just always use -8an because I know its larger than the stock inside diameter.
If 6an were smaller than oem I would assume it would cause back pressure and possibly ruin the oil pump and/or seals.
