NGK Laser Iridium Long Life Spark Plug Box of 4 (SILFR6A)

When it's time to replace your spark plugs, especially on vehicles like a Subaru Forester or a Dodge Charger, you want something that's going to last and perform reliably. These NGK Laser Iridium spark plugs are designed to be a direct OE replacement, meaning they're built to the same standards as what came from the factory. They feature a fine wire center electrode made from an iridium alloy, which has a very high melting point and offers exceptional durability, lasting up to six times longer than platinum. This design helps ensure a stable spark for consistent engine performance.

Beyond the iridium tip, these plugs incorporate a pure alumina silicate ceramic insulator that helps with heat transfer, keeping the plug from overheating. The ground electrode has a platinum pad to promote even wear, which is particularly beneficial for modern distributorless ignition systems. Plus, the trivalent metal plating on the plug body helps prevent corrosion and makes them easier to remove down the road. They also feature triple seals to prevent any gas leakage, ensuring everything stays contained where it should be.

NGK is a well-known name in ignition components, and these Laser Iridium plugs are a solid option for many vehicles. They are designed to provide reliable starts and consistent spark performance over a long service life.
