Thanks for the info. I was going to add the cold air intake filter - I know it increases the sound, but I did some research and it is supposed to add about 12 hp when cold...and then drop to about 8/9 hp. You said that you didn't get anymore performance out of it. Did you add the cold air intake? Let me know, because I don't want to waste the money - if it's not going to add some hp. ciao!
