Product Details

The Honda OEM Front Engine Mount is a genuine factory replacement designed for the 2002-2006 Acura RSX and 2002-2005 Honda Civic Si (EP3) equipped with K-Series engines and manual transmissions.

This front engine mount helps secure the engine and transmission assembly to the vehicle's chassis while absorbing vibrations and limiting excessive drivetrain movement. Proper engine mounting is essential for maintaining smooth operation, consistent drivetrain positioning, and comfortable everyday driving.

Over time, the factory rubber engine mount can deteriorate, crack, or separate due to age, heat, and repeated engine movement. Common symptoms of a worn engine mount include excessive vibration at idle, clunking during acceleration or deceleration, and noticeable engine movement when shifting gears.

Manufactured to Honda's original equipment specifications, this genuine front engine mount provides factory-quality fitment and the reliability expected from OEM Honda components. It is an excellent choice for replacing a worn mount, performing drivetrain maintenance, or restoring the original driving characteristics of your RSX or Civic Si.
