If you're careful, yes.

The part number that you're looking should be 1366220.

Quick eBay search shows this:

Most look okay, but be careful buying used things like this.

just went to the junkyard picked up a used maf off a 96 850 that was t boned for 45 dollars and 50 dollars for the stock air box and maf houseing i decided to buy a the airbox because i snapped the flam trap on the tube coming out of the throttle body hopefullly this lasts a lil while can i unplugg the battery to get the engine light to turn off

[jblackburn]

Cool.

You can do it that way, but it resets the entire computer and makes it re-learn everything. That is actually probably appropriate for this case. Unplug the negative cable and go hit the brake pedal a few times to drain the charge.

For future reference, though, this is how to check/reset codes:

You would want to look in A2 for this.
