Using the DC Sports Cold Air Intake is easy. First, gather all the hardware that comes with the kit. Then, carefully remove the old, restrictive OEM rubber intake pipe from your 2004 - 2007 Accord V6 or 2004 - 2008 Acura TL. Next, install the smooth mandrel - bent aluminum tubing and attach the high - flow air filter. You don't need to cut or modify anything during the installation. When using the vehicle, the intake will work automatically to improve performance. As for maintenance, check the air filter regularly. If it gets dirty, clean or replace it as needed to keep the intake system working at its best. Also, make sure all connections are tight to avoid any air leaks. This intake system meets emissions standards, so you can drive worry - free across the USA.
