Am looking at an 01 2500HD with a 6.0/4L80E - a po has installed a cold air intake, unsure if he used an original MAS or an aftermarket one. Would a 1500's 5.3L stock air cleaner box and ducting be the exact same size and shape as a 2500HD's? I'm assuming all is the same except the MAS, which I'd assume would be calibrated differently between a 5.3 and 6.0 (or would they?)? Anyone know? Thanks. My 1500 is nearing 300k mi, and need another dependable dd, but prefer a 3/4 ton - so am wondering about swapping the stock air cleaner assembly and filter box onto the 2500 HD I'm considering. Just prefer stock and stock parts, would probably stick the cold air intake on the 1500 until it literally drops dead, which may not be for another 200k... Have owned it since new - but things are starting to "go" and would rather have "dd next" in the barn ready to go so I'm not crammed when this one eventually kicks the bucket.
Thanks for any insight.
