6 pcs NGK Laser Iridium Spark Plugs for 2006-2015 Lexus IS250 2.5L V6, Engine Kit Set Tune Up

#ad
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.

Maximize ignitability: the focused flame kernel allows faster combustion and minimizes quenching. Enhance performance: the iridium alloy used in the NGK Laser Iridium is six times harder and eight times stronger than conventional platinum and can handle temperatures associated with the most advanced fuel-injected and turbocharged engines. Reduce punch-through: high-grade alumina silicate ceramic creates a stronger insulator which reduces the risk of dielectric punch-through caused by a spark exiting through the side of the plug. Upgrade your ride: the double precious metal construction exceeds the lifetime and performance of OEM, V-Power, G-Power, and standard grade plugs.
