Description

Spark plugs are sold per piece. The HKS Super Fire Racing MR Series are high heat value plugs that are compatible with M12 long reach type and spark plugs with protruding electrodes that are often used in vehicles with direct injection turbo engines in sports vehicles such as Civic Type R (FK8) and Swift Sport (ZC33S). These are NGK-equivalent heat values of 8 (XLZ only) and 9 to give a higher level of peace of mind when doing light tuning such as increasing boost. In addition to the characteristics of the proven "SUPER FIRE RACING M series", the center electrode is made of ruthenium alloy to further improve reliability.
