For 2003-2005 only. Late 2005 and later models have interference issues with the cam gear area and will not fit.

Control unwanted engine movement..so all the power goes to the wheels, not into moving the engine around on it's mounts. The Stiffy Engine Torque Damper controls engine movement while still allowing a small amount of motion to reduce the possibility of vibration (when properly adjusted).

Get the most performance out of your 350Z sports car with a Stiffy!

Plus, you gotta love the name of this product! ;)
