Product Details

These are NGK IX Iridium spark plugs, sold in a box of four. They're built with a fine iridium tip, which is known for being very durable and creating a consistent spark. This design helps with starting, idling, and throttle response, and it's great for engines that run hotter. The iridium alloy has a very high melting point, making it a solid choice for today's engines, and the trivalent metal plating on the plug helps prevent corrosion and seizing.

NGK designed these plugs for modified or high-performance applications, or as an upgrade over standard nickel alloy plugs. You can expect improved acceleration, better fuel efficiency, and long-lasting durability. This particular plug, the TR55IX, fits a wide variety of vehicles, including many Buick, Cadillac, Chevrolet, and Ford models from the late 70s through the early 2010s.
