Using your Mishimoto silicone induction hose is easy. First, make sure your engine is cool. Then, carefully remove the old stock induction hose from your 2016 - 2021 Honda Civic. Take your new Mishimoto hose and align it with the factory fittings. It's designed to fit directly, so it should go on smoothly. Once it's in place, double - check that all connections are secure. As for maintenance, just give it a visual inspection every few months. Look for any signs of wear or damage. If it gets dirty, you can use a mild soap and water to clean it. Remember, this hose is covered by the Mishimoto Lifetime Warranty, but avoid using any harsh chemicals or abrasive materials that could damage it.
