Guess what they recommend you use on the filter? Snake Oil

 

cant see how its double the surface area . as its still a dome.. k&n on the other hand is a concertina effect.

so i would say its just a box standard foam filter

 

Box or Bog

 

bog

 

x2 simples really

 

ok if the pyramid was hollow then i would say yes with out a doubt. but if not then the air is still being pulled throught the same surface area in the end .
this is why no other foam filter has been made like it before. I.e pipercross, HKS, blitz, greed and so on these people would have a a lot morepower, money and knowledge


but i can see what you say ing about traping the dirt, if you dont clean your filter very much
