I recently replaced the air cleaner, right after i replaced it with a CarQuest replacement filter for my car. I installed it, and it fit well. the box sealed. I started it up, and let it run, gave it some gas, and the noise from the engine was deeper and a little heavy. I compare it to when i was a V8 geek and would flip the air cleaner top an it on a four barrel it would give a deep throaty sound when you got on it.

THe sound is similar to my car now, i'm curious is this is normal?? this deep throaty sound, i can feel it in my gas peddle. Is something wrong??
THanks for any help.
