Just went and bought a package of these armor-all wipes and they work great. Couldn't believe how much dirt was on the inside of my car. They're a little on the expensive side (relatively speaking), but well worth it. Oh, also quick question: I took my throttle body off today to clean it, WD40 the pivots, etc. and noticed a small black box on the front side of it(towards the front of the car). I had pulled this off when I took the throttle body off, and was just wondering what it is. I probably could just go look in my Bentley, but hey, that's what you all are for right? Thanks a lot in advance.
