Hey Kelly!

There is a picture in my garage of foil delete.

It is simply taking the foil and insulation off of the intercooler pipe on the drivers side of the motor. It makes the turbo sound much louder in the cab at cruising speed and acceleration!! Let me know if you have anymore questions!!

link to the garage page

Hope that gets ya there!

I think its where you take the foil looking stuff off the pipe leading from the turbo into in the intercooler. Not sure what it does though.

its stupid. I think its all for looks.....

Removing the insilation does nothing but make the CAC system less efficient....

Looks and noise. I don't think it'l make that much of a difference in CAC efficiency though.

All I know is that I never found any foil under the hood of my 99.....

Doubtful it has any negative effects since the early 99's had this "mod." There were complaints about engine noise and FORD put this on as sound insulation. I think it increased turbo whistle and gave the engine a "cleaner" look without the aluminum foil looking stuff crinklily wrapped around the tube.

In fact, it may be beneficial in 2 ways!
1. A small weight savings
2. Since this is the hot side of the IC tubes and the underhood ambient temps are lower it could actually decrease the temp inside of the tube !!!

It's there to decrease sound. If you don't feel like pulling the sharp foil off and spending an hour or three scraping the glue off depending upon your method, you can order banks dress up kit and they have polished/painted tubes I believe available for your 7.3.

3 other people answered similarly to me before I could answer... darn it! haha...

It's the foil on the left hand side of this picture... there are 4 bolts you need to remove and you can get the tube off.

your wrong there! banks technicooler pipeing and exhaust downpipe come with foil insulation for both of them along with hose clamps to secure it....
