Prothane's motor mount inserts are crafted out of polyurethane, a material much more durable than rubber that can handle intense weight, heat, and pressure. Designed to fill the voids built into your OE motor mounts, these inserts will drastically increase the power transfer efficiency from your engine to the wheels. Since the voids were initially put there to reduce NVH, it stands to reason that filling in those voids will have the opposite effect. Installing Prothane's motor mount inserts may increase your NVH, but the increase to overall performance is worth it to some drivers. To top it all off, Prothane's motor mount inserts are covered by a lifetime warranty

The add isn’t clear on weather it’s one side or both, it’s both sides. Install was easy with new mounts. I wasn’t able to get them to work on the original mounts because they were collapsed enough to where the inserts were off center. Only down side is the engine vibration can be felt some through the cassis but it’s not too bad and got rid of the torque steer
