I Want The Whistle!
i read that K&N CAI's create a whistle which is what i want, but i want the AF1 since it has dynoed to be the best... question, will i get the whitle with the AF1 or do i need to get a throttle body spacer also?? I think i am willing to spend 110 for the TBS even though it does nothing, but whistle, since my 08 5.4L doesnt have a carborator....
P.S. Will a TBS help out on my ATV if i have a jet kit?? Off subject, i know!

o by the way alot of guys out there do not like them but i like mine had it for a year now
Ok, he's wanting the sweet sounds of induction, not a whistle.. LOL...
Thought ya might have been one of them people..
Any quality intake kit is gonna give you that sound.. as said before, if you hear "whistling" then you have a leak somewhere, or a tb spacer installed.
Even better than the whoosh from the induction though is the nice growl you'll hear from under the hood. Not something you'd really think you'd get, but it's pretty sweet..
I can recommend the 3" AF1 (what I have), use that if you aren't getting tuning... The 3.5" if you're getting tuned...
I love the sounds that it makes, there's some better throttle response there too..
