You need to install the ecu first!

 

so it will not work without the ecu install. sigh of relief i thought i killed my car

 

Yes, the SRT intake will not work without the ecu. The ecu is a signal modifier that makes up for the larger than stock intake pipe diameter.

 

also check your mass air sensor for the correct direction

 

The inlet is supposed to be facing the filter right?
