I put the Wix 33032 in there last year,yes it was a liitle thicker but manged to stay in place just fine.Think i paid $5 for it and I was selling Honda parts then,thought dealer cost was too much.
FYI you can use the Yamaha oil filters,same thing,cost 1/3 less.In Canada Honda MFJ filters are $17.95,Yamaha 5GH-13440-20 are $11.95.The 3FV-13440-00 and 5GH-13440-00 are spot on replacements for the discontinued MM9 Honda filter.The Kawasaki ones are the same too but can't remember the numbers,16097-1064,66,70?
