Using this engine mount kit is straightforward but requires attention. First, ensure your vehicle is a 2000 - 2007 Honda Insight (ZE1) with a stock manual transmission. You'll need to use a K20 manual transmission when converting to a K24 engine for the kit to fit properly. It's best to have a mechanic or automotive specialist handle the installation. Once the mounts are bolted down, they can't be returned or swapped out, so double - check the fit before doing so. During normal use, you might notice a bit of engine vibration, which is normal depending on your engine. The mounts are designed for performance driving and help reduce wheel hop. As for maintenance, there's not much you need to do. The mounts have been stress - analyzed and come with a lifetime warranty. Just keep an eye on them during regular vehicle check - ups.
