You can't do that in the Fit TB becuase the size of the TB differs from top, middle, bottom.

 

from the pic of your throttle body
looks like there is plenty of room to do it

 

Maybe above only. It was made in my friends shop and we sure took off a lot but we left some at the top.

 

For those who are in North America, you might want to do this throttle body mod by contacting this guy.

Since the t-body on the Fit is as weird as I have ever seen in recent Hondas. For the record, the Spoon unit is 58mm throughout while the OEM one is 55mm.

I'm sure some port-matching is likely required on the intake manifold making this a more involved modification, particularly those who are not accustomed to working on their own cars. Either way, I'm confident this will give better power but I'm not certain as to how it will affect its fuel efficiency nor powerband.

If it's anything like the B or D series.... then it's a worthwhile mod...perhaps not to start with...but still worthwhile.
