I was curious as to why you chose to put the oil cooler in parallel to the heater and not in series? I am a newbie to car mechanics, and ignorant of many things (which I am enjoying fixing all that with my BRZ), so please don't skewer me if it is an "obvious" reason. This mod looks pretty easy and fun to do, the low cost makes this easier to do sooner rather than later too.
