Odd noise in 2-3k RPM range

mantella87

Hey guys, just wanted to get your input on a noise I've been hearing from my car before I decide if it is worth bringing to the dealership or not. I will try to get an audio clip but it's kind of difficult because it only happens while in gear.

I got my car brand new in 2011 so I understand that our cars can sound like anything from a garbage disposal to an exotic, and our manual transmissions are very noisy, but this is a new noise to me.

I have a manual and I recently had the Injen CAI and Akebono BBK installed. Shortly after I started hearing what I can best describe as crickets while driving around 2-3k RPM. I cannot duplicate this sitting in my garage. The first time I heard the noise was at night so I honestly thought I was hearing crickets outside until I heard the same exact noise during the day. Now I have been able to replicate it on the streets. Car still pulls strong and I can't find anything loose in the engine bay. Could this just be a result of the intakes and is a sound I will have to live with, or is this something the dealer should check out?

Thanks for any feedback!
