Hey,
Just wondering what size tubing is used when connecting to the throttle body for an intake on an Eco. I've heard 3", 2.75", 2.5"...
So which one is it??
-Seth
you can use any i believe, mine is 3", it is big over the throttle body, that is why there is the tighten-able clamps to ensure an airtight seal
Most the the intakes you can buy are 2.75" tubing, so I would go with that.

No, not that, lol.
I'm looking for the OD of the throttle body so I know if I have to buy a reducer from the 3" or not
-Seth
OD on the tbody is 2.75"
I'll get a pic with a veneer later
