Re: air filters
Avoid. It's rubbish.
This is a open foam filter which sits in your engine bay and takes in hot air. The piece of pipe is to deliver a cold supply to the general vicinity of the filter, but that's not much use. One good thing about this type of filter is that it will sound good, but performance will suffer.
Better options are simply replace your standard filter in your standard intake with a better one - eg BMC.
Or a full BMC CDA intake - works fantastically.
Or build a custom airbox - ram air feed into a box from where your engine can such stagnant pressurised air. Some guy on this forum was talking about it and he really knows his stuff. Sorry can't remember his name but do a search on a few keywords.
