Product Description

The Innovative Mounts B90650-75A is a billet aluminum replacement motor mount kit engineered for the 2002-2005 Honda Civic Si (EP3) and 2002-2006 Acura RSX (DC5) with K-Series engines and manual transmissions. It replaces the factory fluid-filled rubber mounts with solid 75A polyurethane-bushed billet mounts, eliminating the engine flex and wheel hop that OEM mounts allow under hard acceleration. The result is sharper throttle response, more consistent power transfer to the wheels, and improved overall drivability for street and light track applications rated up to 400 HP.

Installation is a direct bolt-on to OEM chassis mounting points with no modifications required. K24 engine fitment is supported with the addition of a K20-spec timing belt post mount (sold separately), however K24 transmissions are not compatible with this kit. The transmission mount is also sold separately. Professional installation is strongly recommended, as mounts cannot be swapped or returned once bolted in place.
