It does work. After I loaded mhd sport cooling, my oil temp would not go past 230 and typically bounce between 215 and 230, which was a huge upgrade vs. pre mhd.

The only thing I changed was the thermo and it dropped ten degrees minimum, it targets 220 to open the cooling circuit. It will hit 220 only in stop n go or extremely aggressive driving, valve opens and you can almost watch the oil temp drop. Car stays between 210 and 220 virtually 100% of the time. Even at extremely high speeds.

I also maintain a very clean cooling and oiling system, I'm a little obsessive. Use the liqui moly crankcase cleaner to help keep the varnish and carbon out.

Unless you are tracking, no real need for upgraded oil cooler.

Best 40 I have ever spent.

While the bolts in my differential may or may not be shearing, the oil thermostat I got from AD Engineering works. I brought it up as the one in the link looks just like it. 80 + mph, 103 degrees out, my oil temp is a cool 215 degrees.

Did the research a while back cant recall the details but the dimensions of the thermostat and the design are different vs. Stock.

There is a detailed thread out there from our Aussie counterparts that detail the operation. End of the day oil temps stop rising when it hits 220. Will check later to see if I can find it.

Wax is used for a water thermostat, not oil.

Ozzie they do look very much alike, I imagine they feature a similar design.

I've seen these on fleabay as well and looks ideal for purpose, but correct me if I'm wrong but they don't fit in the 2007 n54?....just the later ones...

Not sure mine is an 09, I would check with bavauto.

I have a dedicated FBO track car here. I've been using LiquiMoly 5W-40 for the last 3 oil changes. It is a good oil and it is WAY WAY better than the "donkey piss" from Mobil 1.

That being said, my next oil change will be with Motul race oil, only because I beat on the car hard at the track.
