I just picked up a spare d16y8 intake manifold on ebay. It is supposedly from a '96 d16y8. I currently have a '98 d16y8. The ebay IM looks like my current manifold. However I noticed that the numbers stamped on the back of the IM are different.

P2K IPT-4 (on my current manifold)
P2K IPT-2 (on the ebay manifold)

Do these numbers mean anything to anyone else? Any other way to make sure that this IM isn't from another civ?

 

mine is a p2k lpt-1 andi wanna know the same thing. bump

 

i beleive the number at the end is the lot number....meaning the time and place it was forged and created...


as long as the first set of numbers and letters are good and the same, then your ok...

basically if it says p2k, and yours is p2k then your good...that code designates it for your engine i beleive

 

Glad to see that people know how to use the search button You resurrected this post from many moons ago

 

How can you tell the difference from an y8 AT manifold vs MT manifold??

 

mt im has the iacv mounted on the back of the im. the auto im has the iacv mounted on the tb.

 

any pix available ?

 

Here's a '00 manifold with air-injection off a manual. note....the large diameter hole on the throttle body flange. That feeds the idle motor, on the back of the manifold. The auto manifolds don't have that.

 

thanks homey... FAWKK!! I got myself a damn AT IM. any tips on how to drill holes in the back of the IM to place the IACV?

 

sooooooooo much easier to sell and get the right one. Auto works fine for y7 mani swaps so you shouldnt lose money.
