This construction has made NGK Standard plugs an OE cornerstone in marine and industrial engines for decades, and the 3323 carries that same proven design forward as a dependable, factory-style replacement rather than a generic substitute.\u003c\/p\u003e\u003cp\u003eBoth the ground electrode and the center electrode tip are nickel, while the center electrode core is copper, and the plug uses a standard ground electrode configuration with 5000 ohms of resistance to help suppress ignition noise. The corrosion-resistant plating on the plug body keeps installation and removal easy even after years of service in a marine engine bay.\u003c\/p\u003e\u003cp\u003eThe NGK 3323 is used across a range of applications, including Dodge and Ford engines, and marine I\/O engines from Berkeley, Crusader, Indmar, and OMC, along with generator applications from Hobart, Ford commercial and industrial engines, farm equipment, and lift trucks from Clark, Ford, Osco, Tow Motor, and Yardster. Always check your engine and maintenance manual to confirm the correct spark plug for your specific application before ordering, since using the wrong plug can reduce performance, hurt fuel economy, or damage the engine.\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 3323\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Plug Designation:\u003c\/strong\u003e AR6FS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5000 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode 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\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 3.58 x 1.1 x 0.79 inches (L x W x H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295133231\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDodge, model years 1993-64\u003c\/li\u003e\n\u003cli\u003eFord, model years 1977-57\u003c\/li\u003e\n\u003cli\u003eI\/O - Berkeley, 1977-1974\u003c\/li\u003e\n\u003cli\u003eI\/O - Crusader, 1975-1974\u003c\/li\u003e\n\u003cli\u003eI\/O - Indmar, 1987-1983\u003c\/li\u003e\n\u003cli\u003eI\/O - OMC, 1974\u003c\/li\u003e\n\u003cli\u003eGenerator - Hobart\u003c\/li\u003e\n\u003cli\u003eCommercial\/Industrial - Ford\u003c\/li\u003e\n\u003cli\u003eFarm - Various\u003c\/li\u003e\n\u003cli\u003eLift Trucks - Clark, Ford, Osco, Tow Motor, Yardster\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eFORD%1120822\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the NGK 3323 spark plug fit?\u003c\/strong\u003e The NGK 3323 (NGK designation AR6FS) fits Dodge and Ford engines, marine I\/O applications from Berkeley, Crusader, Indmar, and OMC, generator applications from Hobart, Ford commercial and industrial engines, farm equipment, and lift trucks from Clark, Ford, Osco, Tow Motor, and Yardster.
