Rotozipping Air Intake
OK... my brainfarting stopped and I put a K&N filter in. When I put it in, I noticed that the air intake kind of ends at the radiator. It doesnt look like/feel like metal but it would seem to me that I could cut a hole in it to make airflow even better
Anyone done this? Is it worth doing and will I screw anything up if I do...
I can take the hammering if I got it coming on this one
Thanks guys

This is also known as porting the snorkel. I cut three 2" holes in my snorkle (2 top & 1 bottom) with a door-lock hole bit. It does open up the intake. I think you should have a K&N installed to do any good. I hear pleanty of air sucking with my porting.
Some folks have done away with the snorkle altogether. I would not recommend this because you may intake more hot air than you should. But, you could remove the snorkle and see....

Yup- did it before it even had a name. 
Now commonly called a Zoodad (named on the "other" SD site), I used a 3" hole saw (fits into a drill) to open a hole in the fiberglass radiator support in front of the snorkle. Theoretically, it creates a "ram air" effect. I've done it to two Super Duty trucks and have gone through lots of snow, rain, dust, bugs, birds, etc with absolutely no problems using either paper or K&N filter.
Some people have taken the basic mod a little further and added ducting from the hole to the snorkle to assure that the air is "rammed" into the housing. I haven't done this yet, but am considering it since the Banks "Ram Air" filter housing doesn't have as long of a snorkle as the OEM housing.

I was going to do the snorkel thing to my K&N FIPK. But I couldn't find the tools I wanted in the garage at the time so I took out the sawzall and rrrrrrrRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR.:-staun
I now ahve a 3"x7" hole in the support. I'm going to use heating duct to ram the air. The opening made a diffeence, though. Every little bit counts.

>Picture boys! I need pictures!!
Sorry about that. I took a few some time back when you asked for them but I guess I kind of forgot to post them!
I finally uploaded a couple to my F350 gallery. After doing this mod, I think you'll see why the Excursion grille is so nice. You need those small squares to keep varmits out of the air intake system.

Thewhiteford - Check out my post from today about the exhaust, I put on a single cat-back from gibson and it made a HUGE difference. I have the same engine.

You're not trying to get me to go back are you?
Speaking of varmits and such, I took the time this weekend to put a screen behind my grille. Works nicely!
Alright now my question...I have a piece of something-or-other right where you cut the hole. Do you know what I'm referring to? It's not plastic but is kinda like a mat material. It is held on my push pins. Where is yours? Did you just chuck it? Or was it never installed on yours?

Looks good. Nice touch on the V10 writing
If I can get the grille out (without busting a nail or smugging my nail polish
). I'll be busy with hole saw too. I'm wondering how a piece of 3" rubber hose would work? I should be able to get a hold of some, it's pretty common around here(lots of oil field trucks)I'll look into it and see what happens.
