EGR PORT TUBE SIZE

[2000_BLACK_SS]

i am looking at buying a lower intake manifold online snd the guy i am trying to buy it from says that it has the smaller egr port tube size and i have no idea at all what size mine would be.

 

the intake is said to be good for the years between 96 to 03 3800 engines. i have a 2000 SS monte carlo.

 

so my question is what size egr port tube do i have? and where could i find this information?

 

thanks for any help.

i ended up just taking off my upper intake manifold and measuring it myself it came out to be 1/2in i.D. 5/8in O.D.
