Definitely adds a growl when the accelerator pedal is pressed, better accelerator pedal response. As others have said, be careful when removing the temperature sensor. I wish they copied the jeep at the sensor port. They give you a sleeve to install the sensor but it's not as good as the twist lock on the jeep part. Well done too.
