NGK PKR7A Laser Platinum Spark Plug
Product Description
NGK Laser Platinum Spark Plug PKR7A. Manufacturer Part Number 3641. These double platinum NGK laser platinum spark plugs feature laser-welded technology. Lasers are used to pinpoint precision welds, reducing excess debris. The reduction of debris decreases the required voltage to bridge the spark gap. Platinum disks welded on the ground and center electrodes reduce the wear rate on both of these surfaces, ensuring great durability and long life.
