oil filter cap wrench for 2004 bmw z4

[Z4-04]

Can anyone tell me what size wrench socket I should get for my 2004 E85 Z4?

 

[G600]

36mm

Thank You and how many flutes should the wrench have?

 

[G600]

6, a 12 will work but 6 is better

Thanks - I ordered one with 6 - hoping it will make it easier to get the cover off and eliminate messing up my cover.

The 36mm, 6 sided cap wrench - socket fit perfectly on my oil filter housing cap on my E85, 2004 Z4
