Product Details
The iridium alloy in these NGK spark plugs has an extremely high melting point, making it well-suited for today's hotter-running engines. These Iridium IX plugs are designed to offer improved acceleration, better fuel efficiency, and longer life compared to standard nickel alloy plugs. The fine iridium center electrode ensures a durable and consistent spark, which helps with starting, idling, and throttle response.
NGK uses a trivalent metal plating on the exterior of the plug, which helps prevent corrosion and makes them easier to remove later on. The tapered cut ground electrode is another design choice aimed at improving starting and idling performance. These plugs are a solid option for upgrading your vehicle's ignition system, especially if you're looking for a more robust spark than what stock plugs offer. They are suitable for modified or high-performance applications, or simply as an upgrade for everyday drivers.
This is a box of four spark plugs, which is the correct quantity for many common V6 and V8 engines. Always check your vehicle's service manual to confirm the exact number of spark plugs required and the correct gap setting.
