The internal diameter of the stock flex tubing is much larger than the
internal diameter of the pipe inside the square air hat on the top of the
engine. If you are worried about the flex tube causing problems then you
should lose the big square air hat as well. In any case, the stock flex tubing
is at least a half inch larger than the throttle body opening. I use the
stock flex pipe on my 4.7 Po-Boy and it stretched over the outside diameter of
the 3" PVC pipe. I think my setup screams and it has a flex point to prevent
stresses and it banging on things. Just something to think about.....

Subject: DML: Po'Boy Intake?
Well guys, I'm finally breaking down and building my own intake. Couple of
questions: (I have a 4.7L)
1) What's the outside diameter of the pipe coming off the airhat? 3.5"?
2) What's the best size K & N Filter to get?
3) I was thinking about getting pipe the same diameter as the pipe from the
airhat, clamping them together, and then going into the cone filter.
Basically, that's what I was going to do. Any comments/suggestions? I do
NOT want to use the stock flex tubing.
Thanks for your help
william
