What spark plugs should I use with a Vortech supercharger system?
Always utilize the stock specified heat range for street legal applications. For continuous heavy-duty racing, off road use only, use one heat range colder than stock and reduce the gap to 0.032 to .040″. (NOTE: the gap requirement varies per the application and intended use). It is suggested that you follow the manufacturers suggested recommendation for spark plugs. Do not use platinum plugs, as they are considered long life spark plugs and are not performance spark plugs.
