The 1720 PLK7RA is a dual platinum spark plug with a 12mm thread diameter, 26.5mm length, and 0.031-inch clearance, strictly compatible with Mercedes-Benz M271/M272 engines. It utilizes a dual precious metal combination of a platinum center electrode and outer electrode, offering excellent wear resistance and thermal stability. The dual platinum electrodes are highly corrosion-resistant, reducing electrode wear and ensuring ignition stability, making it particularly suitable for frequent start-stop or low-speed conditions. Its service life reaches 60,000-80,000 kilometers, reducing maintenance costs. Furthermore, its cold-type heat range design effectively balances the heat dissipation requirements of turbocharged engines, preventing carbon buildup or pre-ignition knocking and avoiding the risk of electrode meltdown.
