The jdm version is a direct wit to the wrx as I understand, while the usdm version needs some modding

I think the JDM one is a bit larger front to back possibly in length as well, I have seen people having the factory A/C line interfere with the fitment of the bigger JDM top-mount.

No fitment issues right here with the USDM one on my WRX.

the jdm one is about 1/2 to 3/4 inch longer, resulting in roughly 10-12% larger in terms of volume on the overall top mount.

they both need extended throttle body hose to work, i've had both on my car.
