Want to get a CAI for my 08 4.7. Goin to get a K&N but i dunno if there are differences. Also where would be the cheapest place to pick one up?

 

Every place I have seen the K&N, it has been about $300.....

 

airram.com 247 with free shipping

 

all decent CAI flow just about the same within 200-250 CFM. You will feel no difference in CAI unless you bought a crap ebay intake and swapped it out for a ramhammer down the road. then you would really feel a difference

 

i dont think there is much difference between a less than $80 ebay one or the $200-250.
basically all a CAI is a pipe with the filter attached to it. some of the ebay ones even come with K&N air filter which is the only thing that would make a difference. for the money youre saving, you would not even notice a difference between brand name pipes and custom made ebay ones
