Champion Spark Plugs Racing Series Spark Plugs -
The world's best-selling spark plug, these economically priced plugs are the choice of many professional boat racers, marine police and fire departments, commercial operations, and recreational boaters. Extra nickel alloy electrodes provide long life and the exclusive triple-coated Ultra Seal shell provides the most protection from corrosion and seizure of any spark plug available today. Plug models with an "R" or "Q" prefix are designed to prevent spark plug-generated interference from affecting electronic devices (such as navigational equipment and radios) while allowing full ignition voltage and amperage to reach the spark plug. In particular, plugs with inductive "Q" type coil suppressors maximize ignition energy with no decrease in arc duration. These performance features add up to the most specialized marine spark plugs available today. Meets ISO and SAE standards as specified by all engine manufacturers.
