When an engine moves excessively in its mounts, energy is wasted. Stillen's engine damper/stabilizer for the 2003-2007 Infiniti G35 coupe and 2003-2006 Infinti G35 Sedan converts this wasted motion into forward momentum. An isolastic mount acts as a shock absorber and dampens unwanted motion. With no hydraulic parts to wear or fade in use, this is a long term solution. Easy mounting uses existing holes and complete instructions are provided.
