Prothane 90-99 Mitsubishi Eclipse Right Motor Mount Insert - Black

What you get here is a single black motor mount insert from Prothane, designed to fit the right side mount on your 1990-1999 Mitsubishi Eclipse. This insert is made from a durable polyurethane material that's built to stiffen up your existing motor mount. When your stock mount wears out, the engine can move around a lot more than it should, leading to sloppy shifts and less direct throttle feel. Adding this insert helps take up that extra space and keeps the engine more firmly planted.

Polyurethane is a great material for this kind of part because it's tough and resistant to the heat and fluids found in the engine bay. By filling in the voids in your stock mount, this insert helps transfer more of the engine's power directly to the drivetrain, rather than letting it get lost in excessive movement. You'll likely notice a more immediate response when you hit the gas and a more solid feel when you shift gears. It's a popular way to get a bit more performance feel out of your Eclipse without going for a full, solid mount that can transmit a lot more vibration into the cabin.
