I had a 2000 P38. The AIT was behind the headlight.
I think they moved it there with the Bosch changeover.
I installed the coils from a 9 cubic foot freezer inside the engine compartment to cool things down.
Mounted the compressor on top of the hood.
I told people it was a supercharger like Mad Max.
Didn't add enough power to compensate for the gigantic inverter I installed to power it.
Then I put a K&N sticker on the back window.
Problem solved.
The vehicle was faster off the line, ran smoother, plus, the gas mileage went up so much, I never bought gas again. And, when chicks saw the K&N sticker, I was fighting them off with a stick.
Changed my life, I tell ya, changed my life.
