Using this DC Sports ceramic header is easy. First, make sure your car is the right model (92 - 95 Honda Civic all models or 96 - 00 Civic EX). Just follow the installation instructions that come with the header to attach it properly. When driving, you'll notice better performance right away. As for maintenance, check the header regularly for any signs of damage or loose connections. If it gets dirty, you can clean it with a mild soap and water solution. Avoid using harsh chemicals as they might damage the ceramic coating. Remember, since it's C.A.R.B certified, you can use it with peace of mind in all states. Keep it away from extreme heat sources that are over 1200 degrees Fahrenheit to maintain the coating's protection.
