NGK Ruthenium Spark Plugs for 2011+ 3.5L Ecoboost F150 and Raptor

Ruthenium HX is available in two designs to best maximize the performance of your engine.

DFE (double fine electrode) maximizes ignitability, while reducing emissions for low-heat engines. This NGK-patented design is recommended for non-turbo applications.

PSPE® (projected square platinum electrode) provides the best ignitability and service life for high-heat engines. This NGK-patented design is recommended for turbo and supercharged engines.

Ruthenium HX provides more complete fuel burn than other precious metal spark plugs, resulting in quicker throttle response, smoother idle and better cold starts.

Ruthenium performs better at high temperatures in various driving conditions compared to the leading precious metal spark plugs.

Ruthenium HX spark plugs are manufactured in an ISO 11565-certified facility following the latest manufacturing processes and regulations. Before coming to market, all NGK spark plugs must pass extensive testing and quality checks, including acceleration, combustions, mechanical vibration and thermal shock tests.

Standard combustion tests look for a spark plug’s ability to maintain stable performance during combustion and engine operation. When compared to conventional spark plugs, Ruthenium HX remains more stable with less dispersion.
