Air intake mod help

If any of you have pics of the air intake mods you have done to your 7.3s I would appreciate seeing them. I am trying to get ideas for making one on my truck which is the early '99.
Thanks for any help.

If you can find a K&N filter tube it works great.....Just leave the actual k&n filter off and put the 6637 on.

I've since shimmed it up with some styrofoam blocks to keep it from wearing through MORE. just make sure the air filter is not in contact with anything when youre done

Thanks for the info and pics. How big is the outlet on the 6637 is it 4" like the stock intake outlet?

Where did you get the piece that goes between the turbo and the rest of the hose? It looks like it maybe says S.S.A. on it. Thanks.

Thanks for the info and pics. I have to replace my turbo inlet tube(cracked) is why I was asking about that. Do you know the inlet size for the stock turbo on the newer '99 and up? Was thinking about upgrading to that hose if it will fit. Mine is 3" on the early'99. Hopefully I can do a cold air intake mod/system soon.

Okay thanks. I left a phone message with Clay about 30 min ago. I had bought injector cups, rings, and rented tool from him recently and found the air tube problem when doing that job.
