NGK Iridium IX Spark Plug Box of 4 (BPR6EIX-11)

You're getting a box of four NGK Iridium IX spark plugs, part number BPR6EIX-11. These plugs are built with a fine iridium center electrode, which is known for its durability and ability to create a strong spark. This design helps with starting, idling, and throttle response, making a noticeable difference in how your engine runs.

The iridium alloy used in these plugs has a very high melting point, making it well-suited for today's engines that often run hotter. They also feature a trivalent metal plating that helps prevent corrosion and seizing, which can be a real headache during installation or removal. This makes them a solid choice for upgrading from standard nickel alloy plugs, especially if you're looking for better acceleration and fuel efficiency.

These NGK Iridium IX plugs fit a wide range of vehicles, including many older models from Chevrolet, Dodge, Ford, and Mitsubishi. They're a popular choice for drivers looking to get a bit more out of their engine's performance.
