thanks for the feedback.

There is a hugh difference in the heavy casing of the OEM compared to the Mann. I think also a hugh price difference between the expensive OEM at the dealer and Mann.

I've used Mann oil filters which seemed good and the air filters seemed similar to the OEM air filter. But the cabin filter seemed ultra-flimsy.
I guess the filter element is the important part.

Is Mann a bargin purveyor for the price conscious? Is Mann quality good?
