Mishimoto Aluminum Fan Shroud Kit for 2006–2011 Honda Civic Si
Improve radiator airflow and engine-cooling performance with the Mishimoto MMFS-CIV-06SI aluminum fan shroud kit. Designed as a direct-fit upgrade for the 2006–2011 Honda Civic Si, this kit includes a polished aluminum shroud and two 12-inch slim electric fans.
Each fan delivers more than 1,150 CFM of airflow, providing a combined rated airflow of more than 2,300 CFM. The formed aluminum shroud directs air through a larger area of the radiator core, helping improve cooling efficiency during idling, low-speed driving, hot-weather use, and demanding performance conditions.
An included adhesive-backed foam strip helps seal the space between the shroud and radiator so the fans pull air through the radiator core instead of drawing air from gaps around the assembly.
The kit fits both the original Honda radiator and the compatible Mishimoto aluminum radiator. Mounting hardware is included for installation.
