The duct is to be installed on the front bumper and it increases the flow of fresh air to the engine bay significantly. The colder fresh air with more molecules produces higher engine power. The duct is designed to be used with the stock front bumper.
The duct diameter is 100mm and the duct hose is available as an option.
Note. Minor cutting of the bumper is required.
