But I think the shocks are different if you have sport suspension (which the 4.6is does). I'd at least call the parts counter at the dealer and have them look up the rear shocks of your X by the last 7 of your VIN, then have them look it up for an 03 3.0i w/rear air for cross-referencing. Just to make sure they are the same before you lose the sport shocks to a bad online purchase.
