Green Filter Cold Air Intake

Anyody know anything about these?  Are they any good?  I am installing a Gibson exhaust on Thursday and was told by the guy at the 4x4 shop to check them out for CAI.  I expressed my concerns with the K&N not fitting and he suggested GreenFilter.
 
Any info is much appreciated.

I have seen them in catalogs, but don't have any info on them.

Thanks- I had already checked out the site and there isn't much info on it.  It isn't too impressive.
