How to Choose the Best Iridium Spark Plugs Buyer’s Guide (2018 Update)

Trivalent metal plating – superior anti-corrosion and anti-seizing properties. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today’s high-performance engines. Designed specifically for the performance enthusiast, iridium ix offers extreme ignitability, improved throttle response and superior anti fouling. Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. The 0.6mm laser welded fine iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect.

Improved cold-starting and acceleration characteristics. Reduced ignition system voltage demands saves wear and tear. Latest evolution in high-performance plug electrode material and new-vehicle applications using iridium plugs continues to increase. Acdelco is an original equipment (oe) supplier and has the experience engineering and manufacturing components that achieve the highest quality standards required by vehicle manufacturers. Iridium tip for maximum resistance to spark erosion and corrosive combustion chamber environment. Spark gap remains virtually unchanged during the life of the plug for increased fuel efficiency and 12-month/12.000-mile limited warranty.

High quality material: purified alumina powder insulator from germany almatis(model: hva fg q0 and full-automatic isopressing; iron shell(model: 20 08 al) and automatic welding/rolling bending; central electrode(99% nickel clad copper ) and 360 degree laser welding iridium & platinum. Reduce the risk: updated design reduce the risk of breaking off during working. Increases fuel efficiency: g-power platinum alloy spark plugs offer superior performance with improved fuel efficiency, lower emissions, and quicker starts. Increased conductivity: increased conductivity and heat control for good overall. Stability: 0.6mm laser welded fine platinum tip reduces required voltage ensuring high durability and a consistently stable spark.

Durability: trivalent metal plating offers superior anti corrosion and anti seizing properties while the triple gasket seal eliminates combustion gas leakage.

Trivalent metal plating has superior anti-corrosion and anti-seizing properties. Designed for fuel-injected and turbocharged engines. Plugs feature a fine-wire iridium center electrode and nickel-alloy ground electrodes for maximum engine horsepower and torque. Precision laser-welded electrode construction. Extreme performance upgrade over oem spark plugs and provide a 40.000 to 50.000 mile service life.

Improve engine horsepower and fuel economy over standard plugs. The same plugs factory-installed on luxury vehicles by automakers such as gm, toyota, honda and mitsubishi. Uses the same high performance laser welding process as the high end iridium power spark plug. Endures extreme temperatures greater than 4.000f associated with high-performance ignition and special fuel systems. Iridium is the most corrosion-resistant metal used in plugs today.
