Description

The NGK LFR6BHX Ruthenium HX Spark Plug (NGK93420) is designed for non-turbo engines. It features patented Ruthenium technology for advanced tip designs (DFE and PSPE) that provide high ignitability, leading to a more complete fuel burn, quicker throttle response, smoother idle, and better cold starts.
