NGK Laser Iridium Spark Plug Box of 4 (SILFR6C11)

When it's time to replace the spark plugs on your 2010-2019 Subaru Legacy, Outback, or Tribeca, NGK's Laser Iridium plugs are a solid choice. These aren't just any plugs; they're built with advanced materials to ensure your engine runs smoothly and efficiently for a long time.

The center electrode on these NGK plugs features an iridium tip, which is significantly harder than platinum. This means it holds up better over time and helps maintain a consistent, strong spark. The pure alumina ceramic insulator is well-built for strength and helps transfer heat away from the plug, preventing it from getting too hot. Plus, the trivalent metal plating on the threads helps prevent corrosion and makes them easier to remove next time around. They also have a platinum pad on the ground electrode, which helps them wear evenly, especially in modern ignition systems.

This set comes with four plugs, which is exactly what you'll need for your Subaru. They are designed as direct replacements for your original equipment, so installation should be straightforward. Just make sure to torque them to the manufacturer's specifications.
