Iridium spark plugs offer 26% faster starts and more concentrated ignition. They deliver higher horsepower and better fuel efficiency for steady engine performance.
A spark plug feeds high-voltage current into the combustion chamber to ignite the air-fuel mixture and drive the piston, enabling engine operation.
Fouling happens when fuel, oil or carbon deposits cover the plug insulator. It causes current short circuits, weakens or kills sparks, leading to hard starts and rough engine running.
Pre-ignition is an abnormal combustion where the air-fuel mixture ignites early via hot chamber spots. It can melt plug electrodes and cause serious, permanent engine damage.
Our smart matching system precisely matches OEM heat ranges and dimensions, ensuring perfect, hassle-free fit for your vehicle.
