ok, i have stock spare throttle body with plenum and with iac and everything... how would i know what year motor it came off of?? not exatcly what year... but if it came off a PI motor or NonPI motor?? are they the same?? heres a pic if it helps....
If I were anything it most likey came off a 1999 maybe 2000. I was also looking at the PCV fitting I cant quite tell but thats also a sign that it was an earlier model one. But hey I could be wrong.
The only difference is the sizing of the PCV nipple on the back of the upper intake elbow. I should know. I have a 2001 Mustang GT with a plenum, which I ported and polished that is from a 97 GT on my car. All I did was used a hose clamp to hold the PCV line on the back in place. Works just fine.
