Well I just finished replacing my air filter and I must say, GM should've thought of a better place to put it. I'm surprised they didn't put it on top of the gas tank There were quite a few small things that made it somewhat difficult to get into the Air Box housing. If anyone out there is thinking about changing out their filters and they've possibly thought about a performance after-market air-filter I would recommend getting the after-market air filter since you'll probably be doing about the same amount of work replacing the OEM air-filter (ok not the same but you'd might as well get one that won't need to be changed out as often as the OEM one). Also while removing the MAF sensor I noticed there was a bundle of wiring that was attached to a bracket but just like GM, it was just dangling freely near the top right side of the engine not attached to anything. I'm thinking of taking it to the dealer so they can see why this bracket is just sitting dangling freely but no telling what they'd tell me. Oh and incase anyone is curious I removed the big air intake at the supercharger and pulled the air filter from the top. The dealer service technician told me I could remove the filter from under the car but I'm not sure if they knew what they were talking about, either that or putting a car on a lift to work underneath it makes a huge difference. Well at any rate my next air filter is going to be an aftermarket one, possibly the K&N intake set-up.
