i am looking into getting a cold air intake. i know i could do the gots mod cheaper but its still a bitch to check and clean the filter. so i am searching the web and found some interesting thinks. i looked at the green filter because it was different. K&N 77 series because it would look good under the hood. K&N FIPK because of performance. i read the 77 series makes 9.38 hp and FIPK makes 13.12 hp. Now any other time i would say bull **** until i saw these dyno sheets.

what do yall think???

 

I have the 57 series intake and it has been great so far. they reason u get more hp out of the plastic tube vs metal tube is because the metal tube conducts heat and it holds onto it a lot longer.

 

that's what i was thinking but it looks so damn good!!! could you tell a difference with the CAI after the install? does it feel like 13 extra horses? also i found it for $246 shipped

 

i could definatly feel a little extra hp but 4 hp difference between 57 series and 77 series isnt that much. i went with the 57 series because it is street legal in california, where i live. it was a really simple install. that sounds like a good price, i work for a dealership and one of r suppliers sells the k&n filters so i got it for just under 200

 

kool sounds good thanks for the help.
