NGK Laser Iridium Spark Plug Box of 4 (DILKAR7B8)

When it's time to replace the spark plugs on your 2017-2020 Subaru Impreza, NGK's Laser Iridium plugs are a solid choice for maintaining that factory-fresh engine feel. These plugs are built to meet the demanding requirements of modern engines, ensuring a strong spark for reliable ignition and smooth operation. They're designed to provide the best combination of performance and longevity, so you can expect them to last.

What makes these plugs stand out is the iridium-tipped center electrode, which is significantly harder than platinum, offering excellent durability. NGK also incorporates a pure alumina silicate ceramic insulator that helps with heat transfer and provides robust strength, while the trivalent metal plating on the exterior helps prevent corrosion and seizing, making future replacements easier. The ground electrode features a platinum pad for even wear, especially important in distributorless ignition systems like the one in your Impreza, and contributes to a consistent, stable spark.

This set comes with four spark plugs, enough for your Impreza's engine. They are designed as a direct OE replacement, meaning they fit right in without any modifications. The copper core inside helps manage heat, and triple seals are used to prevent any leaks.
