Just like topic title, is the MAF the same for TII and n/a within the same series?

 

nope, the springs are a little different. other than that they are the same

 

Like he said, differents springs, but you can subsitute one for the other if you have a fuel computer and a afr guage. I am currently running a S-5 na afm on my S-5 turbo setup, but I also have a s-afc to correct the fuel. So yes and no to answer your question.

 

if you have a NA MAF on a TII engine you wont be able to romp on it.
