Mahle vs Original BMW parts?
I'm replacing the piston rings in my N52. The BMW piston rings are like triple the price of Mahle rings so I picked up a set of Mahle ones, but I'm wondering how risky it is to use them instead of forking out the price of original BMW rings, which are probably manufactured by Mahle, but then I know that with gaskets its best to go with original stuff. Opinions, experiences?
