Using this engine mount kit is a great way to upgrade your 2001 - 2005 Honda Civic. First, make sure to double - check that the kit is compatible with your vehicle, especially if you're using a K24 engine which needs extra modification. It's best to have a mechanic or automotive specialist handle the installation. Once installed, the mounts are not returnable if they've been bolted down. Regarding maintenance, there's not much to do as the kit is designed to be durable with a lifetime warranty. However, keep an eye on the bushings for any signs of wear. You might feel a bit of vibration, but that's normal for performance - oriented mounts. These mounts will help reduce wheel hop and improve your driving experience.
