trd intake question

Can someone with the trd intake for a 2nd gen let me know the (outside) diameter of the the intake tube that goes into the air box?

 

You have piqued my curiosity. Why do you ask?

 

Found a trd intake tube for 40-50 shipped to my door and trying to see what afe dry flow cone filter size to get for it. Would like to order both at same time.

 

Im assuming this is the old trd intake with the alum lid made by afe?

Cuz aem/k&n screwed up the diameter on the newer intake with the plastic cover and it runs lean

 

think its the plastic cover one

 

Ok, so I got the intake tube in and it is 4 1/2" (OD).. should have a filter and couplings by this weekend so I can put it together..
