Default turbo oil filter

Whilst looking into stuff regarding oil coolers I came across this little toy.

Link to product

So an oil filter for the turbo, interesting, I suppose it's a strip down and bath in petrol at each oil change type thing, I'm not thinking about getting one but does any of you guys have one? My instinct is that it is a part that won't do any harm as such except lightening the wallet for a shiny bit of aluminium, care to comment you guys that have lots of turbo knowledge;

Introducing an obstruction for the oil that crosses the turbo may reduce the oil flow , thus the ability to take heat away from the turbo. A slow-flowing oil would also get hotter that a fast-flowing one, with all the disadvantages of this.

Also, why should I be concerned about impurities in the oil going into my turbo? there's nothing there that can get clogged, passages over there are pretty wide and there's no danger that some particules can do any harm. It's not like an hydraulic lifter, for example. Even the bearings don't have less play than the bottom end or the camshafts, for example. Actually, they may have more play, since the turbo spins so fast that may need a larger gap.

If that filter is ment to be installed after the turbo, before the sump, perhaps to retain the crud that shows up when the engine stops and the oil in left in the turbo heats up and start to get cooked, then it is doing some harm, because that crud is ment to go into the sump where it can depositate at its bottom and be flushed away at next oil change.

Just my $.02, I'd like to read what others think too.

Question Cool it...

Just saw an oil cooler for the v6 2.5l being changed due to leakage of coolant. I couldn't imagine a design that uses an immersion seal that is so difficult to redo. It ended with the cooler being replaced at a tidy sum. So the point of this post to inquire as to whether that's a part that's often replaced.
Btw the ng900 went in for a timing belt and idler replacement and left with a huge tab.
