Hi, I was wondering where I could go to optimize the perforamance of my 2002 Intrepid. It runs great now on mid-grade gas and keeps up with traffic w/o a problem. Does anyone know where I could find the resistor that you can stick on your intake air temp sensor so that it gives a fake signal to the PCM? Also where can I find a K & N filter w/o having to order it and waiting for a week? I have searched everywhere from Pep Boys to Autozone and they all don't have it in stock. Thanks in advance for you help.
