NGK Iridium/Platinum Spark Plug Box of 4 (SIKR9A7)

This product is a box of four NGK Laser Iridium High Ignitability spark plugs. These are designed as direct replacements for your vehicle's original spark plugs, offering a good balance of performance and how long they last. They feature a fine wire center electrode made from an iridium alloy, which has a very high melting point and provides a stable spark, even in high-performance engines. The ground electrode has a platinum pad to help it wear evenly, especially in modern ignition systems.

NGK builds these plugs with a pure alumina silicate ceramic insulator that's strong and helps transfer heat away from the plug. The trivalent metal plating on the body helps prevent corrosion and makes them easier to remove later. Inside, a copper core also aids in heat removal, and triple seals are used to prevent any gas leakage. These plugs fit a range of vehicles, including models like the Dodge Dart, Fiat 500, and Jeep Renegade.
