Austin explained that the term “high-ignitability” refers to more than just the spark plug itself. It reflects the complexity of modern engines. These now integrate technologies like turbocharging, gasoline direct injection (GDI), dual fuel systems, and variable valve timing. These engine advancements create new performance demands.
“The demands of the engine today have changed while trying to meet the needs of the customer in relationship to the efficiency of the engine without sacrificing power,” said Austin. “So when we do talk about high-ignitability, we are talking about today’s engine designs.”
Spark Plugs Must Meet New Engine Demands
To meet those demands, many manufacturers now choose ruthenium-based spark plugs. Ruthenium offers superior performance and durability compared to platinum or iridium.
Austin provided some background on this trend. “Ruthenium is the most durable metal alloy that may have some platinum or iridium attributes to it. With that formulation, it’s the best choice for manufacturers on today’s high ignitability engine designs.”
Ruthenium’s metal composition supports efficient ignition under the stress of modern engine technologies. These include high compression, multiple fuel injection methods, and heat variability.
When Customers Should Consider a Ruthenium Upgrade
Austin also addressed the customer question: Should you upgrade to ruthenium plugs if the vehicle didn’t originally require them? The answer: sometimes.
“There are applications where you do not want to change the metal type and tip configuration,” he noted. “But for others, especially those with over 100,000 miles, a more durable, precious metal plug may be a perfect opportunity.”
Counter professionals should reference electronic catalog tools to ensure proper compatibility. These tools confirm whether a ruthenium upgrade fits the specific engine’s design and conditions.
Helping Customers Choose the Right Spark Plug
Counter professionals shouls start with the OEM recommendation. From there, evaluate whether mileage or performance factors justify an upgrade.
Use electronic catalog guides to cross-reference valid options. “High-ignitability” does not always require ruthenium, but many cases benefit from it. Ruthenium spark plugs can deliver long-term value, especially for older engines under stress.
Catch the full episode to hear how to discuss these upgrades with confidence and help customers make smarter decisions.
