Sixity Auto #ad - Deliver outstanding acceleration: the iridium center electrode delivers maximum spark energy to achieve higher ignitability and improved acceleration in comparison with normal plugs. Ensure reliability: extremely durable under high heat and capable of delivering a consistent and stable spark, these spark plugs feature trivalent metal plating that provides superior anti-corrosion and anti-seizing properties.

Maximize ignitability: the focused flame kernel allows faster combustion, and the tapered-center ground electrode reduces energy absorption. Upgrade your ride: level up over oem, v-power, g-power, and standard grade plugs with the NGK Iridium IX Spark Plug that provides superior performance and durability.

Enhance performance: the iridium alloy used in the NGK Iridium IX is six times harder and eight times stronger than conventional platinum and can handle temperatures associated with fuel-injected and turbocharged engines.
