Yep, took my dads out of his 06 the other day. Same as your 04. You will notice the air tube has an additional set of baffles in the elbow at the turbo that your 04 didn't have. It didn't seem to make much more noise than before, though, with the stock air filter and tube. My 04 woke up when I added the Torque-Tube and AFE filter.
