I'm really curious as to what all of the negative chat about "aftermarket" valve stem seals is for. I see the difference from the OE in the intake seal , but no difference in the exhaust seal.
Surely all of these good German companies can't be making bad valve stem seals that they claim "meet or exceed" OE manufacturers specs.
I ordered a set from a local MB dealers parts dept. and got Meistersatz /Conti- CRP , states on package "replaces 103 050 0058".
Any comments?
