. . . but what is the intake, as in PI intake (I do know what PI is), and is it the same thing as an intake manifold. I was getting confused between the PI intake and the PI heads. I now know they are different, but I don't know what each does. Also, where is the intake? Is that where the airtube connects?

I'm still pretty new to this stuff, so please bear with me!

Yes, it is the same thing as an intake manifold...your airtube connects to your upper intake plenum...from which the air enters the lower intake manifold which is what we are talking about here. It is black and plastic. The intake manifold channels the air that is entering the engine into the cylinder heads where it then goes into the cylinders themselves for combustion. The air (and fuel now) then leave the cylinders, go back into the cylinder heads and out the exhaust system.

Check out this site, there is a lot of interesting stuff about engines there.

There is no such thing as a Stupid question dude.... The mroe you ask, the more knowledge you get, but, you can aslo do a search on PI heads or PI intake and you will alot of information.

PI stands for Power Improvement. 1999-UP Mustangs got the PI Heads and PI intake. Here are some pics of 03 PI intake.



If you look at this pic, the cross over is not made of plastic, therfore it's much better than the other PI intakes and it will not crack..

Pic 2 shows how big the holes are compared to the NPI intakes or heads. The NPI heads have like an oval type of shape, therefore, the PI's have more airflow than the NPI.

But if you were hanging around CBS in the '80s, it stands for Private Investigator (you know, like Magnum PI). Hmm, that sounded a lot funnier in my head.
