Yes I can agree with that I bought this from eBay:-
http://www.ebay.co.uk/itm/271097709603?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649All I can say so far the bike runs much crisper and starts much easier than compared with the cone type filter.
I found I had to adjust the mixture screw slightly to find the sweet point after changing the filter types so they must act differently and the foam types are deffinately the type that work for me.
Hope this helps.
