Our take on the NGK Ruthenium Premium RX Spark Plugs Jimny JB74/JC74 (2018-ON)

NGK Ruthenium HX spark plugs are a premium upgrade over iridium and platinum plugs, using a patented ruthenium alloy and high-ignitability tip designs (DFE and PSPE) for more complete fuel burn. They are made in Japan and fit the Suzuki Jimny JB74/JC74 (2018-on). Drivers report quicker throttle response, smoother idle, and better cold starts, with durability that holds up better at high temperatures than conventional precious-metal plugs.

About the NGK Ruthenium Premium RX Spark Plugs Jimny JB74/JC74 (2018-ON)

These NGK Ruthenium spark plugs are made for the Suzuki Jimny JB74 and JC74 from 2018 on. They come as a set of four and are made in Japan.

The plugs use NGK's patented DFE and PSPE tip designs for high ignitability. This gives a more complete fuel burn, which means quicker throttle response, a smoother idle and better cold starts. The ruthenium alloy resists oxidation and holds up at high temperatures.

They are made in an ISO 11565-certified facility. Before release, NGK spark plugs go through acceleration, combustion, mechanical vibration and thermal shock tests. In combustion tests, Ruthenium HX stays more stable, with less dispersion, than conventional spark plugs.
