Do You know what the tiny filter (2" in diameter and 1" high) that sits below the air filter does? Does this one get replaced when you replace the air filter?

One last question that maybe you can help me with. I keep getting a "service engine" light that comes and goes. The previous owner told me that since the added the stage II mods it has always done it. This answer does not sit well and I believe it might have something to do with MAF sensor but the car runs great. To be honest I have not taken it in to find out what code is. I live two hours from the dealership and besides they charge over $50 just to find out what the code is. First and last time the wife's X5 SE light came on, I took it to dealer and it said the gas cap was not put on properly. So I am hesitant to take it in. Any advise will be greatly appreciated.

I don't know where "taos nm" is located, but do you have autoparts stores there that might let you use their code reader? Sure, it's not as good as the DIS/MODIC machines, but it'll get you in a ballpark and we can definately work from there.
