Intake butterfly removal

[Groundpounder1]

Hello all. I've got an '04 and I've read a lot about people removing the intake elbow and butterfly/throttle body and replacing them with an 05+. This sounds simple enough to do but after looking at mine, I was thinking about just removing the butterfly plate.

My question is this. Instead of paying for a new elbow (05+) would I see a similar improvement if I just removed the two allen screws and pulled out the plate itself? I know that the tube/bar would still be in there but can I expect to see some type of improvement in egts/mpg/turbo spool/power? I'm in the military and we don't exactly get paid a lot. This could be a free upgrade. Am I right or wrong? Any input would be greatly appreciated.

I did just that on my '04. I cant say if it improved anything but the plate was gone.

what is the reason for the butterfly in the first place and what kind of gain were you expecting this is the first i have heard of this

The butterfly has something to do with the EGR that was put on late 03's and all 04's. Ford didn't put them on after that because they realized it didn't do anything for EGR. From what I understand, if you have one of these and have had it to a dealership, they just turned it off with a flash and now it's just a huge restriction. A lot of people will take off the entire throttle body spacer (which houses the butterfly) and go with an 05+ intake. I didn't want to spend the money on a new intake so I just decided to remove the 2 torqx screws and pull the butterfly plate off. It takes about 10 min to do and I would think that it would help.

Others that have done the 05+ intake elbow claim lower egt's and quicker turbo spool.

The butterfly will help control the EGR air flow by limiting the intake air and forcing intake suction through the EGR cooler.

Do the 6.0s really have a throttle body? Didn't think any diesels did?

Posted too late. Nevermind

do you have pictures of it so i know i'm taking out the right part

Sorry, I didn't have my camera with me when I did it this afternoon. It's really to do though. Just remove your intake elbow and you'll see the butterfly (if you have a late 03 or any 04). Once you see it, just rotate the butterfly with your hand and you'll see the two torqx screws that hold the plate in place. Just remove the two screws and the butterfly plate will slide right out. The tube that rotates the plate will still remain in there but I would think it should flow better without the plate in there. Obviously, make sure you don't drop the two screws down the intake when removing them.

Has anyone else done this? If so, did you notice any egt or throttle response difference?
