Crank Case Ventilation - Genuine or Aftermarket

[Smudgemanuk]

The crank case ventilation system on my 98 2.8 z3 is original and crispy

My main question is whether the aftermarket parts fit ok

I am asking this because on my dads e46 325 people only recommend genuine because there are stories of aftermarket not fitting properly

Thanks Chris

Can't comment on OEM v after market but I replaced mine with a Febi one with part no 11157520035 and it was a perfect fit.

I certainly try for OEM parts on sensors etc
