Measure where the tube goes into the TB. Whatever that measurement is that's what I would go with.

I've found it easiest to use a 4.0L intake tube, takes out all the hassle.  Nice smooth tube and doesn't have the chambers the 2.5L does.

I thought the 2.5 and 4.0 TB had the same size intake hole (where the air intake is). When I went from the 2.5L TB to the 4.0 my rockit city air tube fit both with no problems.

Are they the same size?

OD vs. ID  OD is the same.  That's what the intake relies on.
