Using this DC Sports intake kit is easy. First, gather all the hardware that comes with the kit. Remove the old, restrictive OEM rubber intake pipe from your 2006 - 2011 Honda Civic. Then, install the smooth mandrel - bent aluminum tubing in its place. Attach the high - flow DC Sports performance air filter. You don't need to cut or modify anything, just use the provided hardware for a simple installation. As for maintenance, check the air filter regularly. If it looks dirty, you can clean it according to the instructions on the filter. Also, make sure all connections are tight to keep the system working well. And remember, since it's C.A.R.B compliant, you can use it anywhere in the USA without worrying about emissions issues.
