About this part

Product Details

This package includes four NGK Iridium IX spark plugs, part number 2669. These plugs feature a fine iridium tip, which is known for its durability and ability to provide a consistent spark. The iridium alloy has a very high melting point, making it well-suited for today's higher-temperature engines.

The design of these spark plugs helps to improve acceleration, fuel efficiency, and overall durability compared to standard nickel alloy plugs. They also have trivalent metal plating, which helps prevent corrosion and seizing, making them easier to remove later. The tapered cut ground electrode is another detail that contributes to improved starting, idling, and throttle response.

These NGK Iridium IX plugs are a solid option for modified or high-performance applications, or simply as an upgrade over your vehicle's original equipment spark plugs.
