Engineered dimensions and a 5000-ohm resistor make them compatible with modern ignition systems while resisting wear under normal driving conditions. The set of four is intended as a direct replacement when the factory part numbers match the vehicle fitment list.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these plugs improve starting and throttle response?\u003c\/h3\u003e\n\u003cp\u003eTheir fine iridium tip lowers required voltage for spark formation and concentrates the spark energy at the gap, promoting cleaner combustion. That can translate to steadier cold starts and smoother throttle transitions without altering your engine management.
