Did you connect all the wires for the box correctly?

did you buy the SRT intake and NOT get the SRT ECU that comes with it? looking at your pic it looks like your missing the heat shield also. n thats not the color they normally come so i guess someone powder coated it. i hope you didnt pay a lot for it if its missing the ecu and heat shield

This one is listed for sale here in the classified section, but the seller has not responded to my inquires. Not sure if it is still available. This is a complete SRT Intake kit. Has the ECU to compensate for the larger tubing and extra airflow. The intake will not work correctly without the matching ECU. An option around this is to replace the tubing around the sensor to the stock diameter.

I didn't, I paid like 80 bucks , and since the only intakes I can find are k&n , weapon r , and the srt intake. I didn't hesitate to grab it but didn't think it would come with its own ecu

WELL, it seems you found your problem, no SRT ecu

lol, goodluck on getting that without having to buy another SRT intake as SRT is closed and Mo never answered anyone for years (except me it seems) you could try him on his personal FB but i dont know another way to get in touch with him and i would be cautious to trust him
i'll pm you
