Intake Manifold Identification

[gto65racer]

Can someone help me Identify the year of these manifolds? I took them off the original motor out of my truck and listed them on ebay. My truck is an 01. The guy that bought them said they are 99 and older. I am the original owner and have never had them changed so I don't understand how they could be 99 and older.

I can't answer your question, but use ebay to your advantage. I'd imagine if you do some searching, you can find some 2000-2003 intake manifolds and compare the pictures.

I am not even sure if they are different.

E99 and before has smaller intake manifold openings (2" i believe)
L99 and later had larger intake manifold openings (3" i think...)

either way, those look small... i would guess E99

This was my understanding also... compairing my E'99 truck to my 2000's, it's a noticeable diffrence.
