By the way a search will get you to the mann + hummel site
if you get stock

www.mann-filter.com

select the english version, unless you want to brush up on your German.

now 102 184 05 01 is a spin on filter which is easy to look at.

Also 104 184 08 25 is a replacable catridge.

It is 159.5 mm high or 6.28" high

Diameter is 62 mm or 2.45" across

Internal diameter is 22 mm or .87"

Internal diammeter of top seal 21mm or .83"

Also according to Mann, filter should come complete with o rings for filter.

Let me know if you are still in trouble, glad to help.
