Sharp Intake noise when quickly pressing acceleration pedal

Fellas... We may have an issue. I recently swapped spark plugs and now I have a very interesting sucking-in-air noise when I rap the gas, not at high rpm's, or repeated. It only happens during the initial press. If I am at a high rpm, and I press a significant amount more, the sound happens again. What could the issue be? I checked the tubing and couldn't find any cracks. I was thinking maybe the spark gaps? but I dont have any misfires. I have the stock v6

 

Sounds like a possible vacuum leak.
