I have been looking at one of the additional oil coolers but they seem extortionately expensive
I was wondering if anyone has had a custom oil cooler added to their car. I was thinking that the easiest way would be to add one in front of the radiator, yes I appreciate this will raise water temps, but if we were to run it in line after the stock oil cooler then the temps would be a bit lower to start with and there would be no cutting etc of the stock unit, brake ducts and the like.
For my mind all we need (just remember I think everything is simple) is
oil cooler core
we could relocate the oil line coming out of the stock cooler into the additional cooler and the outlet from the additional cooler into the stock pump.
Like I said sounds simple but the AR/ER folk are after 7-8 hundred so I suspect I am missing something, or are they charging BMW tax?
Perhaps Pete/Advan might be interested in having a look
