Acura Motor Mount Insert

The Acura Motor Mount Insert by Energy Suspension is a premium polyurethane replacement designed for 2002–2004 Acura RSX and Honda Civic platforms. This Hyper-Flex insert addresses a fundamental wear point in any driven vehicle: the motor mount, which isolates engine vibration from the chassis while maintaining precise drivetrain geometry. As miles accumulate and factory rubber bushings deteriorate, excessive engine movement increases NVH (noise, vibration, harshness), reduces shift feel, and compromises handling response—especially noticeable in performance-oriented driving or aggressive launches.

Energy Suspension's polyurethane construction delivers significantly higher durability than original elastomer mounts while restoring the stiffness and damping characteristics of a new assembly. The black Hyper-Flex formulation balances compliance and rigidity—reducing vibration transmission to the cabin and steering column while preventing the harshness associated with fully solid metal mounts. Weighing just 0.77 lbs and engineered to OEM envelope specifications, this insert retrofits seamlessly into the existing bracket assembly without modification. The polyurethane composition resists oil degradation, UV exposure, and thermal cycling far longer than factory rubber, extending service life to match high-performance demands or simply preserve mounting integrity on aging vehicles.

Enthusiasts and mechanics upgrading 2002–2004 Acura RSX Type-S and Honda Civic Si platforms benefit most from this insert, particularly those seeking improved steering response and reduced powertrain slop without the noise penalty of a solid mount. Installation requires jack support and basic hand tools; no welding or fabrication work is necessary. The insert is compatible with both manual and automatic transmissions in this generation, making it ideal for restoration projects, performance builds, or preventative maintenance on daily drivers where engine movement has become noticeable at idle or under hard acceleration.
