3.4l throttle body size?

Hey guys just wondering what size the throttle body is? I have a cold air intake and need a new hump coupler. Been looking and looking and just can't find good info. Is it 2.5" or 2.75"? Thanks alot guys!

Pretty sure it's 2.75. Let me go measure it real quick.

Edit: Just measured, it's indeed 2.75".

Don't know if you know, but does Toyota use a standard hoses size for all the heater hoses, I'm trying to switch colors and since samco doesn't make a kit I gotta do it myself!

Yeah it is 2.75, the K&N cold air intake uses a 3inch charge pipe, so you need a reducer in order to change the hump coupler that comes with the cold air intake!
