    2003 Acura RSX Replacement Engine Parts Reviews

    Amazing
    They look absolutely awesome once installed. It took me 10 hours to install them with no help. The biggest and most helpful suggestion I can give you is to loosen all of your mounts before you start installing the new ones, make sure your engine is on a jack so it doesn’t fall or brake any of the old bolts. If I would have known this it would have cut the time in half. They are awesome once they’re in though! Pretty dang stiff, my car feels like it has more torque, and less body roll. I highly recommend this upgrade if you have the money.
