no

they wont. your throttle body is drive-by-cable

06 STi (or any STi for that matter) is drive by wire.

you will need to do some modifications.

there is no difference in intakes except for the crinkle red and the location of the holes for the TB.

this is wrong...the manifold will but the throttle body won't...there is no point in doing it other than asthetics. The only difference is the STi has the powder coating.

Except the JDM STi's...they are staying true with a throttle cable.

Here's the skinny... the STi DBW T/B doesn't use the air bypass that the cable driven WRX TB does. It WILL bolt up, the TB will bolt onto it, but it won't work, because (as you'll notice if you look) on the WRX intake there is a big hole at the bottom at the base of the TB, the STi one doesn't have that. It's been said that you can dremel out the STi mani for use on the WRX cable driven TB, but I'm not sure if anybody has done it. All this info came from Phil at Element Tuning.

Correct, there is a technical issue that prevents the swap. If someone really wants the swap they can switch to DBW, for which you'll need the TB, pedal box and assembly, and an ECU that works with DBW. Seems like a big waste for a non-benefit as far as I'm concerned.
