PI intake had long bottem, NPI intake had short bottem. if some one tell you they had pi intake on their 96-98 gt, look at the bottem of the intake to indentify its pi or npi, long is pi, short is npi.
guy try to sell me the gt and told me its had pi engine, first I look at it, and its was npi intake, second oil cap was on the driver side, pi oil cap support to be on passenger side, correct me if im wrong on that.
