12120038349 BMW AIZDEDZES SVECE

AIZDEDZES SVECE is a BMW branded spark plug intended for application in engine electronics. Found in the category of Electrical & Lighting > Engine Electronics > Spark Plugs, it replaces part number 12-12-0-034-091. The technical benefits include enhanced fuel efficiency and lower emissions. Spark plugs deliver the high-voltage spark needed to ignite the air/fuel mixture within an internal combustion engine’s cylinders. These components thread into the cylinder head, positioning the electrode gap precisely within the combustion chamber. Modern spark plugs utilize a variety of electrode materials—including copper, platinum, and iridium—to enhance durability and service life. Heat ranges are carefully calibrated to maintain optimal operating temperature, preventing pre-ignition or fouling. Variations include projected-tip, recessed-tip, and J-hook designs to suit specific engine configurations and combustion chamber geometries.
