I have a source that can get me a K&N FIPK or Airaid CAI on the cheap. Which should I go with?

K&N $225
Airaid $240

Both are new in the box. How hard are they to install?

 

I believe K&N makes the CAI's for Ford, or at least the filters...if that says anything about the quality of K&N. Must be good if they are doing that for Ford

I haven't heard too much about Airaid...although, I haven't personally sought out much information on it either. It could be an excellent piece. I think somebody else would be better suited to chime in on that one.

 

I have a K&N intake and love the sound I get from it and feel the slight performance upgrade I get is worth the $75 i paid for it. However I do hear great things around here about Airaid's intake and it seems to be the first one people recommend for intakes that require a tune.
