Same one found here, used for 15 miles or fewer:
It's just too much for my stock cylinder Puch, even with massive upjetting. This is a nice upgrade over the cheaper foam filters, this one is IMMENSE and has internal wire bracing so it won't collapse or crumble into your carb one day.
I'll include a piece of radiator hose that lets you easily attach it to your Bing.
$15 shipped lower 48. I will ship it oiled up and ready to go (in a plastic ziploc of course).
