Notes: Because of heat range and electrode design, we recommend you DO NOT USE THESE SPARK PLUGS FOR SUPERCHARGED, TURBO, OR NITROUS APPLICATIONS. For those applications use our Brisk Silver Racing Spark Plugs. Spark Plugs with a 17 in the part number are recommended for stock to slightly modified applications. Heavily modified naturally aspirated use spark plugs with 15 in the part number.
