Using this engine mount kit is straightforward but needs some attention. First, make sure your 2000 - 2007 Honda Insight has a stock manual chassis and you're converting to a K20 engine with manual transmission. It's a good idea to have a mechanic or automotive specialist handle the installation. Before bolting the mounts in place, double - check that the kit fits your vehicle. Once you bolt them down, you can't return or swap them out. As for vibration, you might feel a little depending on your engine's series and HP, but the bushings are designed to absorb most of it. For maintenance, since these mounts are built for performance driving, just keep an eye on them during regular vehicle check - ups. If you're thinking about other types of conversions like auto to manual K20 or manual K24, refer to the specific kits mentioned in the product description.
