Plaz gear are great stuff!!!!! Ive only just recently installed the plaz 1000hp intercooler, hot/cold side piping, 4" intake with racebox and process west batter re-location kit. If you have the cold side piping u loose the standard intake. u need either the under battery cold air intake which is easier or... the 4" intake with race box, but this means u will need to re-locate the battery. why didnt u get the hot side piping??? it means u loose the standard cross-over all together??
