Roush Colder spark plugs are specifically designed to handle the high boost pressure and airflow of RoushCharged, turbocharged, and supercharged engines. These high performance plugs help to prevent the preignition and detonation of fuel due to high cylinder temperatures, and they operate on a heat range colder than stock Mustang plugs.
