Anyone know ID of throttle bodies?

I don't own a proper sized inside micrometer, does anyone know the actual inside diameter of the throttle bodies, vs what size K&N will fit over them? Had no luck trying to google it.

ID or OD????

Get a vernier caliper and measure. The latest ones (go to Harbor Freight) are digital and will measure mm and inch. They will also give you both inside and outside measure.
Don't know why you need ID tho. The filters are OD fitment. The K&N's that I used actually had to be relieved a bit on the ID because they were too tight to suit me. 1mm of stretch is nothing,,so don't sweat fitment too much.
If you want to measure with no hassle, take the OE airbox and measure the rubber adaptors (box to throttle body). I could do that but it's late and I'm not going to shop tonite...sorry.

ID is for velocity stacks if I make an airbox, want a smooth match.
