NGK IX Iridium Spark Plug Box of 4 (BPR9EIX)

NGK is well-known for making reliable ignition components, and their Iridium IX spark plugs are a popular choice for those looking to get more out of their engine. These plugs are designed to provide a more consistent and powerful spark, which can lead to improved acceleration, better fuel efficiency, and increased durability compared to standard nickel alloy plugs. They fit a wide range of vehicles, including many Arctic Cat and Polaris models.

The key to the Iridium IX's performance is its fine iridium tip. Iridium is a very hard metal with a high melting point, making it ideal for the extreme temperatures inside an engine. This fine tip requires less voltage to jump the gap, resulting in a stronger spark that ignites the fuel more effectively. The tapered cut ground electrode also helps with starting, idling, and throttle response. Plus, the trivalent metal plating on the plug body helps prevent corrosion and seizing, making installation and removal easier down the road.
