New Products: NGK Ruthenium spark plugs promise better durability

Today’s engines create more power while using less fuel, and this shortens the life of Iridium and Platinum spark plugs. That’s why NGK has created the Ruthenium HX spark plug, which is designed for maximum durability and performance. According to NGK, the spark plugs burn fuel more completely than other precious-metal plugs, providing for a quicker throttle response, smoother idle and better cold starts.
