Hi fellas this is the filter you require when ordering

When you order just let them know ( You require the OEO105 NOT the OEO108 ) as you need the O-RING closer the the end of the snout,
agree they need to update their listing, I will have to let them know next time I go in, but I certainly wouldnt be overlooking a Quality Product because of some prick on the end of the Phone who wont listen to reason, Its a shame really to hear of your experience Drover as every time I have been in there, they couldnt do enough for you, very helpful.
I have successfully used the Cooper Wesfil WCO154 without dramas, as it has the O-Ring down near the snout
