Does anyone know the size for the oil drain bolt washer and the ATF drain bolt washer on a R56 Turbo ?? does K&N oil filter comes with a drain bolt washer? thank you..

 

What K&N oil filter

 

Oh, just saying if an aftermarket oil filter like K&N branded, if it comes with an
oil drain bolt washer.

 

Sadly, I typically reuse my oil drain plug washers. Not a problem so far. I'm guessing the dealer filters come with a new washer. At less than a buck, I'm not sure why you would want to find an alternative to a factory Mini washer. Maybe save thirty cents?

good luck,
Peter
