im hopefully going to put the cold air extension on my injen sri today. i have to unplug the battery to get it in place, so do i need to let it idle for like 10min. when i plug it back up like i did with the ECU and original intake install? im not sure b/c its not really a big change.....

 

If you unplug the battery the ECU resets anyways. So to be on the safe side let the car adjust to the new setup.
