RE: should i buy this header
no it wont it dont care... it comes with both 02 sensor bungs... use them... if you dont want a cel... heres the info...
IF, AND ONLY IF YOU HAVE A 1995 NEON:
You have a few options, which I will explain below.
1.) Simply remove the downstream oxygen sensor, and let the connector
dangle. This will work for some 1995 Neons. Since the 1995 Neons were not OBD-II compliant, you may not get a check engine light. One of the
requirements of OBD-II was to light the check engine light if the computer
did not detect a functional catalytic converter. Because the 1995 Neons
were not OBD-II compliant, the computer may or may not feel the need to light the check engine light.
2.) If you have tried unplugging the downstream oxygen sensor, and got a check engine light, you can try the "resistor trick." This involves
soldering a ¼ watt, 1 megaohm[/b] resistor into the black wire of the
downstream oxygen sensor. This will effectively fool the computer into
thinking there is still a catalytic converter in place, by changing the
output of the downstream oxygen sensor. The resistor trick will only work
if you leave the downstream oxygen sensor in the exhaust piping. You cannot remove the downstream oxygen sensor from the exhaust piping, coil it up, and use the resistor trick; it does not work. I have personally (along with about six of my friends) have tried to use the resistor trick without the downstream oxygen sensor in the exhaust pipe, it does not work that way. The downstream oxygen sensor MUST be in the exhaust pipe for the resistor trick to work.
3.) For 1995, Mopar Performance PCMs will ignore the downstream oxygen sensor, so you can safely remove the sensor without the check engine light popping up. AFX does not manufacture a computer for the 1995 year Neon.
IF YOU HAVE A 1996-1999 NEON:
1.) Go to www.casperselectronics.com, and purchase a MIL eliminator. This clever little device plugs into the engine wiring harness, and modifies the oxygen sensor heating circuit, and converts it into a signal tricking the
computer into thinking the downstream oxygen sensor is still in place. A
MIL PLUG IS NOT JUST A RESISTOR! I cannot stress this point enough, many "uneducated" people think this is just a 39-cent resistor, and they are ripping people off. I personally have one of these, and have used it for almost 20k miles, and I have yet to receive one oxygen sensor related code.

3.) Purchase an AFX RACE PCM. For 1996-1999, AFX PCM will ignore the downstream oxygen sensor, and you can safely remove it without fear of the check engine light popping on. Yes, it is expensive. Yes, it works. 1996-1999 MOPAR PERFORMACE PCM DOES NOT IGNORE THE dOWNSTREAM OXYGEN SENSOR; YOU WILL GET A CHECK ENGINE LIGHT IF YOU REMOVE THE DOWNSTREAM OXYGEN SENSOR WITH A MOPAR PERFORMACE PCM.
