Hard to tell, but I believe coming from in front. I will check the airbox to make sure it's tight.

Nope. Nothing like that. I sounds a lot like the sound in this video at 0:19:

Thanks for this. How did you tighten it?

I had the same sort of noise and that's what it ended up being, unfortunately I don't have a video of the sound. Good luck!

Thanks for commenting guys. Man, I would love for it to be something as simple as that. I don't see anything that appears to be a dipstick for the power steering fluid. How can you tell if it is low? How much is supposed to be in there? Also, do you have a link to the exact fluid I need? Thanks!

I honestly just eyeballed it. Not sure of the exact amount but it's cheap enough that you could just pick up a bottle and add a little at a time so you don't over fill it. I believe if you over fill it, it will just leak out of the reservoir a little bit. This happens at the track too when the fluid heats up and it is meant to "vent" out this way. I have a microfiber towel ziptied around the cap for this reason. Let us know how it goes!
