If you already have aftermarket injector sleeves installed, it is possible that no remover will get them out and you'll have to pull the head. This is not a tooling issue and we won't accept returns after you've attempted to use the tool. This aftermarket tool uses the exact same tap that the OEM tool did before it was discontinued. The reason for the potential issue is that some aftermarket cups have thinner sidewalls so the tap can't get enough bite. You can't simply use a bigger tap because the sidewalls of some aftermarket cups are so thin that you could cut into the head on accident.

*On 4/13/21 this superseded from ST-S924 and the threads changed to 1"-8.
