It might work, but it probably won't work correctly. The MAF sensor output curve will not match the computer without a trip to the dyno for a custom burned chip. Putting your MAF sesnor on the larger housing also results in a similar mismatch.

The wiring connectors won't fit, so you would end up changing the plastic connector shells by releasing the pins, pulling them out the back and then putting them in the 4.6 style MAF connector.
