$70 seems like a lot of cash for a filter that may or may not give you a power increase that is so small you probably couldn't measure it accurately on a dyno.
As far as I can see, it only makes sense if you are racing and trying to gain hundreths of a second. Otherwise IMHO, just put a $10 paper filter in and change it regularly.
