What size reducers for the CAI?

[galantMZD03]

Hey guys need your help i want to order the reducers from importstudio.com
but i need the size for the reducers?
Is it 2.5x2.5 or
2.5x3 or
2.75x2.75 or last but not least
3x3?
also i notice that i need pvc adaptors i know i can get them at Home depot but is there a size i need or anything like that.
Thanks

3x3 reducers from importstudio.com.....they are a little big but they fit once you tighten the clamp.

and 4->3 PVC from homedepot...those are a little big but everything thing is fine once you play with it

BTW, For those of you who has CAI, what size of filter do you have? How can I know if my intake and exhaust are balance?
