I bought a used IAC valve off a eBay and it came off an 8. It is definitely different from the 9 in that it doesn't have the spring and top hat (I'm guessing it's internal).

So can I put an 8 IACV in my 9 throttle body?

Thanks in advance!

 

And is there any difference as to which model is better?

Thanks

 

I've used 3 different ones on my car from all different model years, and they all work the same.

 

Thanks you sir!
