I offered, but it'll look just like under his own hood!
I'm wondering if the MAF attachment remained the same, since we KNOW the 2001+ got a different MAF, with the IAT enclosed in the MAF.
It may be as simple as drill and grommet a hole in the 2001+ aftermarket intake to mount the IAT. Frankly, I don't understand the issue. They offer one for your year, buy that one. If you already bought the wrong year, return it for the right one. If you're looking at one on flea-bay and want it even though it's for a newer year, you'll take your chances that it won't fit the MAF, plus you have to drill a hole.
