Product Details
The fine iridium center electrode on these NGK Iridium IX spark plugs is six times harder than platinum, offering exceptional durability and a consistent spark. This advanced material choice is perfect for today's high-temperature engines, helping to improve acceleration and fuel efficiency. These plugs are a solid option for modified or high-performance applications, or simply as an upgrade over standard nickel alloy plugs.
NGK uses a trivalent metal plating on the plug body, which helps prevent corrosion and seizing, making installation and removal easier down the road. The tapered cut ground electrode is designed to improve starting, idling, and throttle response. This box contains four spark plugs, suitable for many common V6 and V8 engine configurations found across a wide range of vehicles like the Chevrolet Traverse, Ford F-150, and Cadillac CTS.
