A fuel injected engine is not that likely to suffer from carburator icing (as there is none installed), so it does not need a carburator heating.
On the other hand, it might very well get the air filter clogged up - be it via a bird strike, icing or whatever else might sneak up the air path. So past the air filter, there will be some commonly spring-loaded to closed position tabs. They should be opened by suction, if the filter lets too little air pass, or they can be actuated manually. In the F33A I flew some years ago, this was done during pre-flight to ensure the doors were still movable.
So carb heat and alternate air are two fundamentally different things.
