NGK Laser Iridium Spark Plug Box of 4 (DILKAR7B8) for Select Subaru 2017-2020

Fits select 2017-2020 Subaru Impreza and Crosstrek models.

NGK Laser Iridium High Ignitability spark plugs (DILKAR7B8) are engineered for original equipment applications requiring precise ignition timing and maximum service life. These plugs feature a laser-welded iridium-tipped center electrode paired with a platinum pad on the ground electrode. This dual-precious metal construction provides superior wear resistance and consistent sparking, maintaining high ignitability even in demanding distributorless ignition systems.

The DILKAR7B8 is built with a high-grade pure alumina silicate ceramic insulator for superior dielectric strength and thermal conductivity. A 98% pure copper core aids in heat removal to prevent overheating and pre-ignition, while triple seals prevent combustion gas leakage. The exterior shell is finished with trivalent metal plating to provide long-lasting anti-corrosion and anti-seizing properties without the need for additional thread lubricant.
