Re: 1998 gt intake question
to install the pi intake on the non pi heads will require adapters, i think livernois makes a kit with the intake to swap it over. expect a 15 hp gain installing the intake. no tune is neccessary and the swap is straightfoward, use all of your existing electronics. now if you are trying to reinstall the non pi factory intake i do have one for it but u need to reuse your aluminum coolant crossover in the front.
