If you installed aftermarket parts on your car and your cel went on you need a part.
www.autotube.net has it. mine has been on for about 25Kmiles still no check engine light.

 

Just thought i would let ya know that i have talked to the well i guess you could say lackey for the head srt8 mopar program and he told me that even the mopar headers and cat-back systems will set off the check engine light if you drive it like you stole it.

We have installed a few at our dealership 1 for the mopar headers and car-back and cold air kit the customer is very happy and as of 2 months later he has not called back saying his light was on but i just thought i would point it out that they said it might come on even with the mopar stuff on it.
