Question for 2Gen CL/TL and 3Gen TL owners

[CleanCL]

My question is:

Do the Honda/Acura J32A1 engine Premium model, 2001-2003 CL-P/ 1999-2003 TL-P; and the J32A2 engine Type S, 2001-2003 CL-S/ 2002-2003 TL-S; and the J32A5 engine 2004+ TL/ 2007+ TL-S have the same throttle body?

I ask because I found a 3/4" thick throttle body spacer that fits the 2004+ J32A5 engine, but I'm not sure if I have the same sized throttle body...

Do you actually get noticeable gains from the ''butt dyno''?
