HKS Super Fire Racing MR45HLZ Ruthenium Spark Plug (NGK 9) - Honda Civic Type R FK8 - Single

The HKS Super Fire Racing MR45HLZ is a Ruthenium-alloy spark plug from the MR series, an NGK 9 equivalent heat range HL-type plug developed for the Honda Civic Type R FK8 2.0 turbo and similar M12 long-reach protruding-electrode applications. The ruthenium center electrode improves fuel burn for quicker throttle response, smoother idle, and better cold starts, with extended life over standard plugs and a colder heat range for tuned cars.
