These just seem to have hit the market a few weeks ago and was wondering if anyone is interested in getting a group buy for these going. Heres a little snipet of what I read,
A revolutionary new filter technology available for your BMW.

The filter is placed in an aluminium heat shiled which helps to funnel as much air into the filter as possible. The shield helps to create a vortex to maximise the air throug the filter, it also acts as a shield to protech it from engine bay heat.

The top of the filter has a moulded twist in to help spin the air into a vortex for improving air flow through the filter.

Facts:
Air intake diameter: 79 mm
Filter shield lenght: 180 mm
Filter shield diameter: 132 mm

This is a throughout tested kit, and comes with all nedded parts, such as vent hose, aluminium shield, filter, fitting items.

The filter is made so it can be cleaned for longer last.

Picture

Yeah, i've been to the site through TMS who are now handling Green Filters.

When i saw this setup for the first time, i had to wonder if the designer was on crack?:laugh

If you could show some test data i.e. dyno graph(s), I would be interested only if the improvements are as generous as they seem.

How much in USD?

When I think green I dont think filters they are quite funky looking, I will see if the persons who did the tests will be send me over some real dyno graphs to post
