This is an insert to fit into the original mount to limit movement of the engine, providing stability under acceleration. A small increase in noise and vibration is to be expected. This should be considered a performance upgrade.
Upper mount fitments include: A CLASS W176 INC. A45 AMG (2012-2017), CLA CLASS W117 & W156 (2012-2016), GLA CLASS W156 (2012-2017) - see below for lower mount.
