question about afe filters

im looking to get an afe stage 2 si cai soon. before all the haters come out and say im pissin my money away im fine with not getting a bunch of extra mpgs out of it i just want it for the throttle response and a lil extra seat of the pants hp's. but i was wondering, even though i see a lot of people talking about the pro dry filter, which filter i should choose. the pro 7 the pro 5 or stick with the pro dry. i dont mind oiling the filter when needed, have had k&n's in the past. anyone have any input on this? also i see that a lot of folks found theres for sale for like $250 im only seeing them for around $350. am i missin something or did prices just go up that quick? thanks for the help.

 

hmm wonder how all those guys got one for 250 then. they said it was on Amazon but wonder how come so much cheaper.

 

You can STT, but if I'm not mistaken someone posted a link for the AFE CAI for $295 including shipping.

 

Whats stt?
