K16TNRS9 DENSO Spark Plug - Nickel

The Spark Plug - Nickel from DENSO (MPN: K16TNRS9) is sourced from China and has supplier-listed dimensions of 24 x 24 x 85 mm. It is typically used within the Electrical & Lighting > Engine Electronics > Spark Plugs category of automotive replacement parts. Dimensions are provided by the supplier and may include packaging dimensions. 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.
