NGK Iridium Premium Spark Plug (BR9EIX)

When you're looking to get the most out of your engine, especially if it's been modified or you're aiming for higher performance, upgrading your spark plugs is a smart move. These NGK Iridium IX spark plugs are built with a fine iridium tip, which is known for its extreme hardness and durability, lasting much longer than standard platinum plugs. This fine tip design helps ensure a consistent and strong spark, which translates to better starting, smoother idling, and improved throttle response.

The iridium alloy used in these plugs has a very high melting point, making it ideal for the higher temperatures found in today's engines, whether they're stock or performance-tuned. You can expect improved acceleration, better fuel efficiency, and overall durability from these plugs. They also feature a trivalent metal plating that helps prevent corrosion and seizing, making them easier to install and remove down the road. This set includes four plugs, which is a common quantity for many 4-cylinder engines, but they are also suitable for other applications like motorcycles and ATVs.
