Using this mount kit is simple. First, make sure you've got the right fit for your 2006 - 2011 Honda Civic Si with a K - Series engine and manual transmission. Don't try to use it with a K24 transmission as it won't work. It's best to have a mechanic or automotive specialist handle the installation. Once installed, you'll notice improved driving performance, with reduced wheel hop and better response. But keep in mind, because these mounts are stiffer and don't have the dampening oil containers of stock mounts, you might feel a bit of vibration depending on your engine. After installation, don't try to return or swap the mounts if they've been bolted down. Also, always check if the kit fits your vehicle before you start the installation process. There's no need to notch or trim the hood, as it's a direct - fit bolt - in kit. As for maintenance, since it comes with a lifetime warranty, if you encounter any issues, reach out to the manufacturer. Just drive and enjoy the enhanced performance this kit provides.
