It is treated with corrosion-resistant plating that keeps installation and removal straightforward over repeated service intervals, and its ceramic insulator houses a copper-core center electrode with a nickel tip alongside a nickel standard ground electrode for consistent ignition performance. This plug corresponds to OEM equivalent part number BPR8ES and is rated at 5000 ohms of resistance, with a standard ground configuration and an M14x1.25 thread. As an NGK Standard plug, it is built to the same specification NGK uses for original-equipment applications, giving it comparable fit, spark quality, and durability to the factory plug it replaces. It is intended as a direct maintenance replacement for the 2021-2022 Ski-Doo MKZ Sport, powered by the 2 cylinder, 600cc, liquid-cooled 2-stroke Rotax EFI engine. Always confirm the recommended spark plug in your engine's maintenance manual before ordering, since installing the wrong plug can reduce performance and fuel economy or cause engine damage. Packaged as a single plug, NGK Spark Plug 3923 is a straightforward swap for scheduled tune-ups or replacing a fouled or worn plug.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e NGK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 3923\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Equivalent Part Number:\u003c\/strong\u003e BPR8ES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5000 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Configuration:\u003c\/strong\u003e Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode Core Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Core Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Tip Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e M14x1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Material Type:\u003c\/strong\u003e Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295139233\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 count\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eSki-Doo MKZ Sport (2 cylinder, 600cc, liquid-cooled 2-stroke Rotax EFI), 2021-2022\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eBPR8ES\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does NGK spark plug 3923 replace?\u003c\/strong\u003e NGK Spark Plug 3923 corresponds to OEM equivalent part number BPR8ES, so it is the correct replacement wherever that plug is specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs BPR8ES the same plug as NGK 3923?\u003c\/strong\u003e Yes, BPR8ES is the OEM equivalent part number for NGK Spark Plug 3923;
