I did a massive write up on this in f7power, tested every filter i could find.
The new renault mann ones drop the pressure about 0.5 - 1 bar compared to the old renault mann ones. I phoned mann and they said the particulate filter size has changed.
The main problem i found with most filters was that the oil pressure wouldnt rise as the revs rose. The old renault mann ones would rise upto 4-5 to 5 bar if you really hammered it. The new ones go to about 3 bar and just stay there at a constant oil pressure.
Champion is not as good as the old renault mann ones, but its almost as good.
I have no empiricle data as to how this effects the top of the engine in a real world setting, i can only guess.
