The OEM engine mounts are the only way to go.

Just think of them as a wear item that your replace regularly.

All of the aftermarket engine mounts that claim to “firm up shifting” et. al., are disastrous.

Even if you get a “slightly” firmer one, they ALL trigger the engine knock sensors and you will actually LOSE horsepower and torque. I have seen it on the dyno.

Just stay away from them all.

Good luck.
