Using this replacement mount kit is quite straightforward. First, make sure you've contacted us to check the stock and wait times as it might be on back - order. Then, if you're not a mechanic or automotive specialist, it's best to have a professional install it for you. Before bolting the mounts in place, double - check that the kit fits your 2001 - 2005 Honda Civic (EM2/EP2) with D - Series engines and either an automatic or manual transmission. Remember, once the mounts are bolted down, they can't be returned or swapped out. During performance driving, you may notice a slight vibration depending on your engine's series and HP, but this is normal as these mounts are designed to reduce wheel hop and increase driving response. For maintenance, there's not much to do as the mounts are built to last with a lifetime warranty. Just keep an eye on them during regular vehicle check - ups to ensure they're in good condition.
