The temp gauge in the Boxster is terribly inaccurate. What may register 180 at the gauge, is more accurately 205 to 210 actual coolant temp. As mentioned earlier, Porsche runs the temps high due to emissions control at the expense of engine longevity. I run the LN 160 degree stat which keeps coolant temps down, translating to lower oil temp.

If you decide to keep the stock t-stat and run the higher temps, at least do your engine a favor and change the oil every 5 to 6k miles.
