pi -vs- npi identifying

[wolvee123]

I think the last owner of my stang may have done a intake swap but I dont know how to tell the difference between PI and NPI... The GT seems like it has a lot more power than the 215 stock hp from the factory....

Hey everyone this is my first post so dont blast me if I posted in the wrong area!

How do I tell which intake is on my stang and is there any way to tell the diff on the heads? thanks

Like the 10th picture down shows the two intakes side by side, The PI in that pic is painted, but normally they ar ethe same color.

Look along the right top side of your intake, and if it has this number: M738E, it is a NPI intake more than likely. Also, look into your valley below the intake, the PI intake will basically touch your block. The NPI wont even come close. I had all the same questions when I bought mine. Good luck.

Doesn't the PI have an aluminum coolant crossover, and the Non is plastic?

I may be wrong, but I think when Ford started replacing the faulty intakes on NPI cars they also came with an aluminum crossover. Plus, I think I have seen them on ebay before.

They didn't start using the aluminum crossover until 2001 so there are PI's that are all plastic.

A good way to tell is to look at the intake from the top/front. If the very first runner after the Coolant crossover goes to the passenger side (left) its an NPI Intake. If it goes to the drivers side (right) It a PI Intake.
