Thanks for the legwork on this! I might just have to make a few of these... one for the road and one for the track bike!

i plan on seeing what i can get at the bike show?

Can't we just fit 4 socks to the velocity stacks??

if you want to but its not going to filter jack shit buddy!

if you could get it jetted right it would sound superb. not sure if it would be tractible on a road bike though?

had some socks on a pair of webber 45 dcoe's never had any problems or and muck behind the socks on road, or track.
keep the socks oiled after cleaning and they work well, admittedly (under laboratory conditions) not as good as a cotton gauze or standard paper filter

whats socks did you use? toddler ones? i got stacks here they have grown out of if you need any!

I think you seriously believe i'm talking about socks that slide on feet........ :D
this is what i had in mind http://img204.echo.cx/img204/8262/mk1clearout1269yk.jpg
