oil cooler lines are in the 120 - 150 range I believe but the oil cooler for a new one i'm not sure what Mazda OEM is but I know PWR makes one for our cars.. probably costs more than my right kidney is worth though https://www.nopistons.com/forums/pub...#>/biggrin.png

you can replace in stainless for under $300.

oh-yeah, its always a good idea to use new crush washers on banjo bolt fittings everytime you take them loose, otherwise, yes they will leak...
