This set includes four genuine NGK R7437-9 (No.4654) Racing Spark Plugs, engineered for maximum durability and performance under the harshest engine conditions. Each plug features a fine wire iridium-tipped center electrode for improved ignitability, increased durability, and enhanced anti-fouling capability.
These plugs are obviously expensive however if you are running big power then you need to guarantee your spark and fuelling are correct so in my opinion its worth the extra cost
