NGK Iridium Spark Plugs Box of 4 (BKR7EIX-11)

These are NGK Iridium IX spark plugs, part number 6988, designed for a range of vehicles including many Acura, Honda, and Saab models. They are a solid choice for anyone looking to upgrade from standard nickel alloy plugs, especially in modified or high-performance applications. The fine iridium tip is built to last and ensures a consistent spark, which can lead to improved acceleration, better fuel efficiency, and overall durability.

What sets these plugs apart is the iridium alloy used for the center electrode. This material has a very high melting point, making it well-suited for the higher temperatures found in performance engines. The tapered cut on the ground electrode also helps with starting, idling, and throttle response. Plus, the trivalent metal plating on the body helps prevent corrosion and seizing, making them easier to remove down the road.
