NGK Iridium IX Spark Plug Box of 4 (CR6HIX)

NGK is a well-known name for ignition parts, and their Iridium IX spark plugs are a solid choice for many vehicles. These plugs are designed to give you a better spark, which can lead to improved acceleration and better fuel efficiency. They are a good upgrade over standard nickel alloy spark plugs, especially if your engine runs hotter or you're looking for a more consistent spark.

The fine iridium tip on these plugs is very durable, and the iridium alloy itself has a high melting point, making it well-suited for today's engines. You'll also find that the tapered cut ground electrode helps with starting, idling, and throttle response. Plus, the trivalent metal plating on the plug body helps prevent corrosion and seizing, making them easier to remove later on. This set includes four spark plugs, which is a common quantity for many 4-cylinder engines, but they fit a wide range of ATVs, motorcycles, and even some classic cars like the Aston Martin DB2.
