Anyone fitted the ramair/raidHP/Wolf filter?

It looks to fit directly onto the throttle body so looks tidy and no issues with rubbing. Also a lot cheaper but does have a seperate breather filter using the orrginal pipework which looks a little naff but does the job.

Where can you buy green filters and has anybody tried to fit directly to the throttle body without the bend pipe? (I know you will need a seperate breather)
