1. Better Overall Performance
Iridium spark plugs use precision engineering and laser-welded surfaces to make the spark plug more responsive and efficient. Iridium electrodes provide the spark plug with greater heat and corrosion resistance and improve charge retention.
2. Long Life
Dual Iridium spark plugs can withstand higher temperatures and pressures during the combustion process, which extends their life. Dual Iridium spark plugs are estimated to last four times longer than traditional non-precious metal spark plugs and 125% of similar platinum-based spark plugs.
3. Durability
Iridium is an extremely tough, durable metal with a high melting point, which enhances the overall manufacturing quality of the materials it is made of. It is an excellent choice for high-pressure, high-temperature environments, such as inside gas combustion engines.
4. Limited Visible Damage
One problem with all commercially available spark plugs is that they crack and carbonize over time and repeated use. The strength of iridium allows it to last longer without damage and maintain a consistent electrode gap.
5. Reduced Voltage
Iridium conducts electricity better, which means that a lower voltage is required across the metal to create a spark. This helps extend the life of each iridium spark plug, as there is less gradual damage caused by high currents.
