Intake piping? What size?

[Gamble]

I am bored and figured I want to make my own intake pipe from the box to the throttle body.
What size does everyone use when doing this? I'm assuming factory is about 2.25"?
I'm thinking I need a 90* and maybe 2 45* angles?
Post up pics of your intake weather you bought it or made it.

^ I never calculated. I did it because I needed the extra airflow with my TRD SuperCharger. I've pulled off 30.7mpg with that, a TRD SC, and Headers/Exhaust.

Did you make that? What type of bung is needed for the iat sensor?
It looks to be 2.5" ? And neck down at the throttle body to 2" or 2.25?

I believe the adapter to the intake manifold is 3" to 2.25". I used a $40 honda intake from autozone/kragen.
The bung came with the intake kit, but the hole was too small for the sensor to fit. I ended up cutting too much off the new bung and decided to use some silicone to set the sensor in the hole.

You got that at autozone? I wanted to try something a little different and use a cone filter in a box and hard pipe it to get rid of the restriction but still maintain a factory look.

Heres a few old pics. Are you looking for something like this?
